How Does Auto Aftermarket Parts category Work?

While global trends set the broad context, the automotive aftermarket has important regional differences. Here we provide more detailed analysis for the United States, Europe, and Asia-Pacific – three major markets that together account for the majority of worldwide aftermarket revenue.

MOTEC are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

United States

Market Size and Growth: The U.S. is one of the largest and most mature automotive aftermarket markets. In , the total U.S. aftermarket (including light vehicles, medium and heavy-duty) is projected around $534 billion. Focusing on light-duty vehicles (cars and light trucks) – which comprise the bulk of this – the market was about $389 billion in and expected to reach $400+ billion in . Growth has been robust in recent years: after a pandemic-induced dip in early , the aftermarket rebounded with ~9.7% growth in and ~8.1% in , buoyed by strong consumer demand and used car usage. From onward, growth is forecast in the ~3–4% range annually through , returning to a more normalized pace. The U.S. car parc is huge (~290 million vehicles in operation) and aging (average age 12.5 years in ), which supports ongoing aftermarket spend. By , even with EVs emerging, the majority of vehicles on U.S. roads will still be combustion-engine, so the traditional aftermarket will remain substantial. The U.S. aftermarket also includes a significant heavy-duty segment (parts and service for commercial trucks, etc.), which adds tens of billions in value on top of the light-duty “auto care” market.

Structure and Channels: The U.S. aftermarket is highly developed with a mix of big national players and many small businesses:

• On the distribution/retail side, a few large companies have considerable market share. For example, the four largest auto parts retailers (AutoZone, Advance Auto Parts, O’Reilly, and Genuine Parts Company/NAPA) together account for a significant portion of parts sales, especially in the DIFM channel through their wholesale programs. There are also big warehouse distributors like Motown Automotive, Worldpac (which specializes in import car parts distribution), and others serving repair shops. E-commerce (Amazon, RockAuto, etc.) has gained traction; Amazon is estimated to be a top-ten player in U.S. auto parts sales now. However, brick-and-mortar distribution remains critical due to the need for rapid delivery to service shops.
• On the service provider side, the landscape includes ~230k+ independent repair shops and service outlets, plus ~17k franchise new car dealerships (each with a service department). There are also thousands of specialty shops (tire stores, oil change franchises, etc.). The independent vs. dealer split for service is roughly 70/30 as mentioned, favoring independent aftermarket. The franchise chains (Midas, Monro, Firestone Complete Auto Care, etc.) hold a notable share in specific niches (e.g. tire replacement is dominated by specialist chains and independent tire dealers).
• Customers: U.S. consumers have a relatively high propensity for DIY – about 22% of aftermarket product sales by value are DIY (though the share of actual vehicles serviced DIY is smaller, since DIY jobs tend to be lower-cost tasks). There’s also a large do-it-for-me contingent that relies on the extensive network of shops. Fleet maintenance is significant too (rental car companies, delivery services like UPS/FedEx, etc., often have in-house maintenance or national service agreements).

Regulatory and Market Characteristics: The U.S. aftermarket benefits from strong legal support for competition (Magnuson-Moss, etc.) and a culture of consumer choice. The Auto Care Association and MEMA (Motor & Equipment Manufacturers Association) are active industry bodies. Emissions and safety inspections vary by state (some states have annual inspections which guarantee a baseline of repair demand, others have none). The Right to Repair agreement in (stemming from the Massachusetts law) led automakers to voluntarily share diagnostics data with independents nationwide, which has helped maintain access. Now the focus is on telematics as mentioned. The U.S. also has one of the most developed collision repair industries, with insurance companies playing a key role (they often dictate use of aftermarket vs OEM parts in claims – currently, aftermarket collision parts are widely used to save costs).

Recent Trends: In the last five years, the U.S. aftermarket has seen:

• Digitalization: Widespread use of electronic parts catalogs, shop management software, and growing e-commerce. Brick-and-mortar retailers enhanced omnichannel services (buy online, pickup in store; curbside pickup; ship-to-home).
• Consolidation: Example, Advance Auto’s acquisition of Carquest, and more recently, discussions of potential mergers (there were rumors of Advance and AutoZone, though nothing materialized as of ). Repair shop consolidation in collision segment (large MSOs – multi-shop operators – like Caliber Collision expanding).
• COVID impacts: A dip then surge in demand. Supply chain disruptions did cause some parts shortages in –, which led to higher parts prices (inflation). Some garages had to wait for certain components, affecting customer wait times.
• Electrification: EV market share in U.S. new sales reached about 5-6% in . While EVs are a small fraction on the road, aftermarket players are starting to prepare (training for high-voltage systems, acquiring equipment for EV service like battery diagnostic tools). Tesla and other EV-makers have been building their own service networks, but independent EV repair startups are appearing too. By , EVs could be perhaps 20-30% of new sales in U.S. (varies by scenario), so the impact will grow mostly beyond for aftermarket.
• Legislation: The Right to Repair at the federal level is being watched closely. SEMA and others are pushing for it to ensure modifiable software and open data access. Also, emissions regulations are causing changes – e.g., more states adopting California’s stricter rules could increase the need for EVs or emissions equipment work in those states.

In summary, the U.S. aftermarket is large, mature, and dynamic, characterized by well-established supply chains and a strong culture of vehicle maintenance. Growth will be steady rather than explosive, and the players are focusing on efficiency and adapting to new tech to maintain profitability in a slowly evolving market.

Europe

Market Size and Growth: Europe’s automotive aftermarket (including EU countries, UK, and broader Europe) is similarly large. Western and Central Europe combined had an aftermarket size of roughly €240 billion in , and this is expected to grow to around €300 billion by . More recent estimates put the Europe aftermarket at around $200+ billion in for light vehicles alone. Growth in Europe is generally modest – on the order of 1–2% annually in mature markets (like Germany, France, UK) – mainly tracking inflation and slight increases in vehicle parc. Some higher growth is seen in Eastern Europe and Turkey due to rising car ownership. The European parc is about 400 million vehicles (if including Russia; EU plus UK is around 300+ million). Average vehicle age in the EU is about 11 years, but with wide variation (e.g., ~8 years in Luxembourg vs ~17 in Greece). Europe’s aftermarket growth drivers include the aging fleet and people keeping cars longer (especially in Southern/Eastern Europe due to economic reasons). By , Europe will also have a higher share of EVs in its fleet than the U.S., which may temper aftermarket growth late in the decade.

Structure and Channels: Europe’s aftermarket is fragmented along national lines but has been consolidating:

• Distribution: Europe historically had many country-specific distributors and parts traders. Over the last decade, giants like LKQ entered Europe and acquired companies in the UK, Germany, Benelux, Italy, etc., to form a continental presence. Also, European buying groups such as GroupAuto or AutoDistribution coordinate independent distributors across countries. Some big distributors: Euro Car Parts (UK, now LKQ owned), Stahlgruber (Germany, also LKQ-owned), Inter Cars (Poland, a major Eastern European distributor), among others. There’s also a strong presence of manufacturer-affiliated programs: for instance, Bosch operates its own distribution and service network for Bosch parts.
• Retail and Service: The concept of DIY retail auto parts stores is less prevalent in Europe than in the U.S. European consumers more often rely on garages for parts and installation. There are some retail chains (e.g., Norauto and Feu Vert in France which cater to DIY and also do installations), but most parts are sold business-to-business to workshops. Workshops get parts through local distributors or directly from manufacturer service networks. Independent garages are numerous; Europe has a very dense network of small workshops, often family-run. At the same time, automakers maintain extensive authorized dealer networks. Thanks to regulations (MVBER), independent garages can access parts and info, but dealers still retain a sizable share especially for newer cars. In Europe, it’s estimated that independent aftermarket accounts for roughly 50-70% of service volume, with variations by country (higher independent share in UK/Germany, lower in some Mediterranean countries where people stick to dealers longer).
• Online parts sales have grown in Europe too. Marketplaces like eBay are used, and there are local online retailers (e.g., Oscaro in France, Autodoc which operates across Europe online). Autodoc, a Berlin-based online retailer, reportedly exceeded €1 billion in sales, reflecting the potential in online parts commerce in Europe. However, many European DIYers still buy through local motor factors or accessory shops.

Regulatory Environment: Europe’s aforementioned Block Exemption Regulation shapes the market. The current MVBER was extended to , confirming the regulatory stability for independents. The EU also has stringent type approval and safety standards – meaning aftermarket parts often have to meet certain certifications. One unique aspect in Europe is the prevalence of insurance and leasing: a higher share of cars is leased or under warranty and maintenance contracts in the first years, which funnels business to authorized networks early in a car’s life. But once out of those contracts, cars often move to independents. European consumers are cost-conscious and often switch to independent garages for cars older than ~5-6 years to save on repair costs.

Trends:

• EV and Hybrid Adoption: Europe is moving faster on EVs – countries like Norway (over 80% of new sales electric in ), and strong growth in Germany, UK, France. By , a significant minority of vehicles in operation in Western Europe will be electric. This is expected to flatten aftermarket growth in the long term, since certain revenue streams (oil changes, etc.) will decline. However, near term (next 5 years) the effect is limited as the parc still has mostly ICE vehicles. Meanwhile, hybrids (HEVs and PHEVs) are common, which still require traditional maintenance plus new items (battery checkups).
• Consolidation and Networks: We see more garages joining multi-brand workshop networks to get access to training and branding (Bosch Service, 1Link, etc.). Also, insurance companies in Europe often have preferred repair networks for collision, pressuring independent body shops to join networks or lose business.
• Digital Service Records: A trend is that many newer cars have their service history logged digitally (often accessible only to authorized networks). Independents need access to update these records to avoid hurting car resale values. Efforts are underway to create neutral platforms for service records accessible by all authorized users.
• Economic factors: Europe’s aftermarket growth was a bit slower during , but government stimuli (like Germany’s temporary VAT reduction and scrappage schemes) didn’t directly focus on aftermarket. As of , inflation and high energy costs in Europe affected consumers (people might delay some maintenance). However, cars are needed for daily life, so the impact is modest. The war in Ukraine had some effect on new car supply and part of Eastern Europe’s economy, but aftermarket there is still expected to grow as used car imports into Eastern Europe have actually increased (many used cars from Western Europe get exported east, providing a steady flow of older vehicles that need parts).
• Right to Repair Updates: European industry groups (like FIGIEFA and CLEPA) continue to lobby for stronger telematics data access. The extension of MVBER in was a positive sign. The EU is also working on legislation around access to in-vehicle data which will significantly affect the aftermarket by mid-late s.

In essence, Europe’s aftermarket is mature but heterogeneous. Northern and Western Europe have high car ownership and well-established service networks, with a tilt toward professional servicing. Southern and Eastern Europe have older fleets and possibly more DIY due to cost considerations (e.g., Poland or Russia traditionally had more owner repairs, though this may change). The market is competitive, with OEMs and independents coexisting – often the same large suppliers serve both channels (Bosch, Valeo, etc., providing parts to dealers and independents alike). Future growth in Europe is likely slower than global average, but the region will remain highly significant in value and a leader in dealing with new challenges like EVs and connected car regulations.

Asia-Pacific

Market Size and Growth: The Asia-Pacific region is the fastest growing automotive aftermarket globally, underpinned by large developing markets. It’s also diverse, including established markets like Japan and Australia, and huge emerging ones like China, India, and Southeast Asian countries. As of mid-s:

• China: China’s aftermarket has expanded enormously. In it was ~€90 billion; by s, estimates vary, but it likely crossed $150+ billion. McKinsey projected China alone could reach ~€430 billion by , which would make it the second-largest after North America, perhaps even rivaling it. China’s vehicle parc passed 300 million in (including ~270 million cars and light vehicles). The annual growth of car parc has slowed to mid-single digits as the market matures, but the mix of vehicles is aging – many of the cars sold in the early s are now exiting warranty and needing more repairs. This creates a rapidly growing independent aftermarket demand.
• India: India has about 300 million vehicles as well, but a majority are two-wheelers. Still, it has roughly 40–50 million cars/light trucks. The aftermarket in India for passenger vehicles was estimated around $10–15 billion in recent years, but growing at 8-10% annually. Including two-wheelers and commercial vehicles, India’s overall aftermarket is larger (two-wheeler parts and service is a big business on its own).
• Southeast Asia: Countries like Indonesia, Thailand, Malaysia have growing car fleets. Southeast Asia combined might have ~90 million vehicles. These markets see strong demand for basic parts (tires, batteries) and are growth markets for multinational parts makers.
• Japan: Japan is a large but very mature market. It has ~78 million vehicles and one of the highest vehicle ages for a developed nation (average over 13 years now, since people are keeping cars longer than before, a shift from the past where they’d replace cars more frequently). Japan’s aftermarket is significant (perhaps $30–40 billion range) but growth is flat due to a shrinking population and high new car quality. Much of Japanese aftermarket is served by OEM-affiliated channels (auto makers have strong dealer networks and parts supply).
• Rest of Asia-Pacific: South Korea, Australia, and others are also notable. South Korea’s aftermarket is somewhat closed and OEM-dominated (Hyundai/Kia’s networks), though an independent sector exists. Australia and New Zealand have vibrant aftermarkets heavily influenced by U.S./European models (a lot of DIY and independent shops; Australia has ~20 million vehicles, average age ~10+ years).

In aggregate, Asia-Pacific (including China, India, etc.) likely surpassed Europe in aftermarket size and is on track to eventually be the largest regional chunk. The growth rates in Asia-Pacific are higher: many markets are seeing 5-10% annual growth in aftermarket demand. One source estimated Asia’s overall aftermarket CAGR at ~7% through , well above global average.

Structure and Characteristics:

• China: China’s aftermarket has been evolving from a very fragmented, informal market to a more consolidated and organized one. Traditionally, many car owners serviced their vehicles at dealership service centers at least during the warranty (in part due to a perception of quality and warranty protection). After warranty, independent garages (of which there are vast numbers in every city) capture a lot of business, often offering significantly lower prices. Parts distribution in China has been fragmented with layers of wholesalers and many small retailers in local markets. But recently, large players are emerging:
  • OEM dealership networks are expanding their own aftermarket offerings to retain customers (e.g. offering discounts for older cars, creating secondary brands of parts for older vehicles).
  • Independent chains: Some domestic companies and entrepreneurs are rolling up repair shops into branded chains (like “Tuhu” for tire and auto service, or Carzone, etc.), often with investment from tech companies or private equity.
  • E-commerce in China is extremely influential – platforms like Alibaba (Tmall Auto) and JD.com sell huge volumes of parts and even service packages online. Consumers can buy parts online and either install themselves or bring to a shop. Many shops source parts from online wholesalers as well.
  • Regulations: The Chinese government introduced guidelines to promote a more orderly aftermarket (e.g., requiring automakers to provide technical info and encouraging use of certified aftermarket parts). There’s also a push to root out counterfeit parts; major brands have programs to ensure authenticity.
  • The result is that China’s aftermarket is in flux: high growth, with players jockeying for dominance. International companies (Bosch, Continental, etc.) are deeply involved, setting up networks and training programs. Local manufacturers of parts (many) also supply both domestic and export markets; China is a global hub for aftermarket part production.
• India: India’s aftermarket is still largely unorganized. There are countless independent mechanics and small parts shops. Car owners often go to neighborhood garages for cost reasons. OEM dealerships do service newer cars but tend to lose customers quickly after warranty due to cost. Parts distribution in India involves many importers and wholesale markets (like the famous Kashmiri Gate market in Delhi for parts). However, organized retail is emerging: companies like Bosch have “Bosch Car Service” centers, and TVS Group runs a large parts distribution network. Online retail is nascent but growing (e.g., Amazon India sells auto parts, and startups are trying B2B e-commerce for garages). A challenge in India is parts quality – counterfeit or sub-par parts circulate, so brand-conscious consumers sometimes insist on OEM parts. The growth prospects in India are strong as vehicle ownership rises and the huge two-wheeler parc also transitions to needing more service for four-wheelers.
• Southeast Asia: Often these markets have a mix of Japanese influence (since Japanese carmakers dominate sales, their dealer networks are strong) and local garages. Thailand, as a car manufacturing hub, also has many OEM suppliers and a decent parts export industry. In many ASEAN countries, consumers commonly use independent roadside mechanics for smaller jobs and save dealer visits for major issues. The aftermarket is growing as vehicles sold in the s boom are now aging.
• Japan & Korea: These are more structured. Japan’s aftermarket includes the “Shaken” inspection system: vehicles must pass a rigorous inspection every 2 years after the first 3 years on the road. This leads owners to either invest in repairs or sell the car. Many owners opt to replace their car around the first or second inspection due to high costs, historically feeding a large export of used cars and parts (which actually supply other countries’ aftermarkets, like many used Japanese cars go to Africa or Southeast Asia). Those that keep their car use a mix of dealer service and independent. Notably, Japan has very strong auto parts retailers for DIY and enthusiasts (like Autobacs and Yellow Hat stores), which are big one-stop shops for parts and accessories – reflecting a still present DIY culture for certain upgrades (especially among enthusiasts). South Korea has been historically dominated by OEM service due to warranty and cultural preferences, but an independent aftermarket exists and has been slowly growing after changes in monopoly regulations by OEMs.

Trends in APAC:

• Urbanization and Traffic: In Asia’s mega-cities, heavy traffic leads to high wear (e.g., brake wear, clutch wear) and also many minor collisions (body parts demand). So in places like Jakarta, Bangkok, or Mumbai, there’s strong business for both mechanical and collision parts.
• Motorcycle Aftermarket: Unique to developing Asia is the sheer number of motorcycles. While our focus is on automotive (cars/trucks), it’s worth noting that two-wheelers need parts and service too – and many small shops cater to them. As people upgrade to cars, those same shop owners often expand into servicing cars, etc.
• Digital Leapfrogging: In some Asian markets, they are leapfrogging straight to app-based ecosystems. For example, in China, apps like WeChat integrate car services; you can schedule a service or find a mechanic through super-apps. Companies are offering “doorstep service” via apps in India (mechanic comes to you), albeit at small scale.
• OEM Strategies: Automakers in Asia (whether Japanese, Western, or Chinese OEMs) have realized the aftermarket potential. Many are expanding their genuine parts offerings and even creating second-line brands for cheaper parts for older vehicles (for instance, some OEMs sell a budget line of parts via dealers to compete with aftermarket prices). Chinese OEMs, in particular, have large domestic customer bases to retain.
• Electric Vehicles: China is the world leader in EV adoption by volume. Over 25% of new cars sold in China in are electric. This means in a few years, a significant portion of the vehicle parc in cities will be EVs under warranty (EV powertrain warranties can be long). How the independent aftermarket deals with EVs in China will be telling. We already see EV-specific repair shops appearing (for things like battery health checks, etc.), but many independents might lose business like oil changes. Conversely, EVs still have suspension, tires, body, and other parts similar to ICE. Other APAC countries are slower on EV adoption (India and Southeast Asia are just starting with small EVs or two-wheeler electrification; Japan is more hybrid-focused). So the traditional aftermarket remains strong for now.
• Local Manufacturing and Export: Asia-Pacific (esp. China, India, Taiwan, Thailand) is a huge source of aftermarket parts for the rest of the world. Trade policies and quality improvements in these manufacturing hubs affect global supply. For example, improved quality of Chinese-made parts has made them more accepted worldwide, intensifying competition for established brands.

In summary, Asia-Pacific’s aftermarket can be characterized by high growth, increasing formalization, and tech-driven change. The region will likely account for the largest share of new aftermarket revenue added globally through . Companies are investing heavily there, from setting up distribution centers in China’s interior, to training networks of Indian mechanics on newer cars, to tailoring product lines for local needs (e.g. hardy suspension parts for rough roads). The regulatory environment is gradually aligning with global norms (e.g., China’s antitrust guidelines mirroring EU style rules, India considering right-to-repair). By , APAC could be the powerhouse of the aftermarket, with China possibly the single biggest national market, and many homegrown firms rising to global prominence in this sector.

The automotive aftermarket is highly competitive and features a mix of parts manufacturers, distribution specialists, retailers, and service chains. Here we profile key players and the competitive landscape:

Parts Manufacturers (Suppliers): The top automotive suppliers by revenue – companies like Robert Bosch GmbH, Denso Corporation, ZF Friedrichshafen AG, Continental AG, Magna International, Aisin Corporation, and Valeo – all have significant aftermarket operations in addition to supplying OEMs. For instance, Bosch is often cited as the world’s largest automotive supplier and offers an enormous aftermarket portfolio (spark plugs, brakes, electronics, filters, etc.) under its brand. It also operates the Bosch Car Service network globally, which is a key differentiator (tying parts supply with service). Continental (through its ATE, VDO, etc. brands) and ZF (with its Sachs, Lemförder, TRW brands) similarly are major players in aftermarket brake, chassis, and transmission parts. Denso (part of Toyota group) is strong in Asia and North America for engine management and AC parts. 3M is a unique case – known for adhesives and tapes, it’s a big supplier to body shops (for paints, sandpapers, etc.) and thus considered a significant aftermarket company . Goodyear, Bridgestone, Michelin – the tire giants – dominate the tire replacement market (each with 10-15% share globally in tires). They differentiate by brand reputation, technology (e.g. run-flat tires), and having extensive installer networks.

Many suppliers sell to both OEM and aftermarket; some also do consumer marketing (like NGK Spark Plugs, now Niterra, which is a leader in ignition parts, advertises its brand to end users). Localization is a strategy: for example, Schaeffler (Germany) targets emerging markets by expanding its LuK, INA, FAG aftermarket brands for transmission and bearings. Delphi Technologies (formerly part of Delphi/GM, now owned by BorgWarner) provides fuel and engine management parts and has a strong presence in the independent garage market.

Competition among parts suppliers revolves around coverage (having the right parts for many vehicle models), quality, brand trust, and increasingly speed to market for new parts (after a new car model launches, how quickly can aftermarket version parts be offered). Some suppliers, especially in collision parts, face competition from low-cost manufacturers in Asia. This has led to a tiered market – premium brands vs. economy brands. Often, a large supplier might offer multiple brands at different price points. Profit strategies for suppliers include focusing on high-margin niches (like performance parts or specialty chemicals) and expanding into fast-growing categories (e.g. electronics, software, ADAS calibration equipment).

Distributors & Wholesalers: A few global players stand out. Genuine Parts Company (GPC), through its NAPA network, is huge in North America and has also acquired businesses in Europe and Australasia (Repco in Australia). GPC had annual revenues around $19 billion in , making it one of the largest aftermarket companies . LKQ Corporation (US-based) grew rapidly by consolidating the salvage parts industry and then moving into new aftermarket parts distribution; LKQ’s revenue (>$12 billion) comes from supplying collision and mechanical parts (and it owns Euro Car Parts in UK, etc.). These big distributors compete by offering one-stop-shop inventory breadth and logistics speed. MEMA Aftermarket Suppliers reports indicate North America has over a dozen distributor companies exceeding $1 billion in sales.

In Europe, besides LKQ, large groups include Mister-Auto (Stellantis-owned e-distributor) and regional giants like Inter Cars (Poland) which is expanding EU-wide. Japan’s distribution is dominated by OEM networks and parts trading companies affiliated with OEMs (like Toyota has Toyota Parts distributors). China is seeing the rise of consolidated distributors like Sinomach Automobile (state-backed) and CASIC entering aftermarket distribution, as well as private ones like 3Treey.

Distributors differentiate via availability and service to garages. Many offer value-added services like training for mechanics, inventory management software for shops, or loyalty programs. The competitive threat to traditional wholesalers is e-commerce and OEMs possibly selling direct. Thus, we see wholesalers going digital (creating online ordering platforms for shops) and sometimes vertical integration (e.g., distributors buying retail chains or vice versa, to secure their customer base).

Retailers & E-Commerce Players: In the U.S., the competitive landscape among the “Big Four” retailers (AutoZone, Advance Auto Parts, O’Reilly, and NAPA/GPC) is intense but relatively stable – each leverages store footprint and commercial delivery programs. AutoZone leads in store count and has strong financial performance (with sales around $16 billion in ). O’Reilly and Advance similarly are ~$10–14 billion range each. They focus on store network expansion, private label product lines, and speed of delivery to local installers as key differentiators. Walmart is a peripheral competitor, selling a lot of volume in certain categories (batteries, oil) due to low prices, though not offering full service or parts expertise.

Online, Amazon has become a top retailer by volume for certain parts (especially accessories and simple parts that consumers feel comfortable ordering). Amazon’s strengths are price and convenience, but it lacks the auto-specific support that traditional players have – yet Amazon is reportedly investing in better compatibility tools and possibly partnerships with service centers for installation. RockAuto (a purely online retailer) competes on a huge catalog and often low prices (shipping from central warehouses). They serve a global customer base to an extent, exporting parts to various countries. eBay Motors remains a marketplace for both new and used parts; many small sellers and even big distributors use eBay to clear inventory.

In Europe, Autodoc (online) is a big competitor to brick-and-mortar motor factors. Traditional retailer chains exist in pockets (like Halford’s in the UK – more of an auto accessory and bicycle retailer, but they do some parts and installation; or Stahlgruber’s retail counters in Germany). Marketplace platforms also arise – e.g., in Russia (before economic changes) there was a thriving online market for parts.

Service and Repair Chains: On the service side, competition is more local and fragmented, but notable chains include:

• Franchise workshops: Midas, Meineke, and others in North America; Midas also operates in Europe. Quick lubes like Jiffy Lube (Shell-owned) handle a large volume of oil changes in the U.S. Firestone Complete Auto Care (owned by Bridgestone) and Goodyear Auto Service centers tie tire makers into service provision, giving them a sales channel for tires plus maintenance.
• Dealership networks: Each OEM’s dealers collectively form a “network” that competes with independents. For example, Toyota’s dealer network might advertise service specials to lure back Toyota owners. These networks’ strength is in brand-specific knowledge and warranty ties. They compete by emphasizing genuine parts and sometimes longer warranties on repairs.
• Independent shop networks: Many independent shops join affiliations like TechNet, NAPA AutoCare, or Carquest Technical Institute, which provide marketing and training – collectively these form a pseudo-network to compete with franchises.

Major Company Profiles:

• Robert Bosch GmbH: A German conglomerate, #1 global auto parts supplier. In aftermarket, Bosch is known for spark plugs, batteries, wipers, brakes, diagnostic equipment, and more. It has a global distribution and its own service network (16,500+ Bosch Car Service garages worldwide). Bosch’s differentiation is quality and innovation (e.g., it invests in new diagnostics for independent garages). It had automotive technology revenues of over €45 billion (not all aftermarket, but a portion) and continues to invest heavily in software for connected repairs .
• AutoZone, Inc.: The largest U.S. aftermarket retailer, with 6,000+ stores in North America and recently expanding to Brazil. Known for customer service focus and robust inventory, AutoZone targets DIY and commercial customers. It has its Duralast private label brand which is a key to margins. AutoZone’s strategy is steady growth in store count and leveraging its hub-and-spoke distribution for quick replenishment.
• LKQ Corporation: A unique player combining recycled OEM parts (from junkyards it owns) with aftermarket parts distribution. It operates in North America and Europe with numerous subsidiaries (Keystone for collision, Euro Car Parts in EU). LKQ’s scale in collision parts is a differentiator; it supplies many body shops with cheaper alternatives to new OEM parts. It continues to acquire smaller firms to grow.
• O’Reilly Automotive: A strong U.S. retailer with a dual market model (DIY retail and robust professional delivery). O’Reilly has been praised for its inventory breadth and deep integration with local markets (through acquisitions of regional chains). It’s highly profitable and invests in store-level engagement (like store staff building relationships with local mechanics).
• Denso Corporation: Japan-based, major global supplier (part of Toyota Group). Aside from OEM business, Denso serves aftermarket primarily in Asia and North America with products like AC components, filters, spark plugs (its Iridium plugs are popular), and sensors. Denso competes closely with Bosch in many categories.
• Michelin & Bridgestone: These leading tire manufacturers control large shares of the replacement tire market. Each not only makes tires but also has distribution networks and their own retail outlets (Michelin owns chains like Tire Centers in the U.S. and has the Euromaster franchise in Europe; Bridgestone owns Firestone stores, etc.). Their competition is mainly each other and other tire brands like Goodyear, Continental, Pirelli, etc. Tire makers differentiate by technology (Michelin known for longevity, Bridgestone for run-flat tech, etc.) and by brand segmentation (each has multiple brands including mid-tier brands they own like Bridgestone’s Firestone line or Michelin’s BFGoodrich).
• Regional standouts: In China, companies like FAW Parts, Dongfeng Parts (affiliates of automakers) are big in their brand’s aftermarket. Additionally, Alibaba’s Tmall and JD.com are essentially huge “players” though they are platforms. In India, TVS Automobile Solutions is a rising company consolidating aftermarket services. In Europe, Schaeffler and ZF have strong aftermarket divisions (ZF Aftermarket integrated TRW’s program, making it a big supplier in brakes and steering). Sogefi and Mann+Hummel are major in filters.

Competitive Strategies:

• Product Breadth vs. Specialization: Some companies (like large distributors or retailers) aim to offer everything – “one-stop shop.” Others specialize deeply (e.g., a company only making engine gaskets, but being the best at it). Both strategies can succeed; large players sometimes acquire niche specialists to broaden their catalog.
• Brand and Marketing: Aftermarket brands often invest in marketing to build recognition (e.g., Monroe shocks run ads saying “Ride safe with Monroe”). Companies sponsor motorsports or have certification programs to convince mechanics and consumers of quality. Brand loyalty can be strong, especially among technicians (who might trust a particular brake pad brand for its reliability).
• Pricing and Private Labels: Many retailers introduced private labels (AutoZone’s Duralast, O’Reilly’s MasterPro, etc.) to offer lower-cost options that also yield better margins for the retailer than selling third-party brands. Competing on price is a constant theme, particularly for commodity parts. However, ultra-low-cost entrants (often imported generics) push incumbents to either cut prices or differentiate on quality/warranty.
• Cataloging and Data: A less obvious but crucial competitive area is having the best parts catalog (the database of what part fits which vehicle). Companies like Advance Auto have invested in predictive algorithms to stock the right parts locally. Catalog accuracy and ease of use (for example, how good the website or lookup tool is) can influence customer choice, especially for online businesses and for professional installers ordering parts.
• Availability and Speed: Being able to deliver a part within an hour can win a sale from a garage that can’t wait days. AutoZone, O’Reilly, etc., heavily compete on who can deliver faster from their local hub to the shop. Amazon introduced same-day or next-day on some parts in metro areas, raising the bar. In Europe, quick delivery is often via motorbike couriers in cities. Companies invest in more distribution centers and local warehouses to cut delivery times.
• Service Integration: Some parts suppliers provide extensive support – training mechanics on new systems (Bosch, for example, runs training centers), or technical hotlines to help troubleshoot issues. This builds loyalty to their brand of parts. Similarly, retailers offering services (like free check engine light diagnostics in the U.S. parts stores) use it to draw customers in.
• Global vs Local Competition: The biggest companies operate globally (Bosch, Continental, 3M, Michelin, etc.), but the aftermarket still has many local heroes – a regional distributor or a well-known garage chain in one country. Competition exists at multiple levels; global suppliers compete for contracts at large buying groups, while a local repair shop might just be competing with the one down the street.

Market Shares: It’s hard to pinpoint exact global market shares because the aftermarket is segmented. But we can say:

• No single company has more than a single-digit percentage of the global aftermarket, because it’s so fragmented.
• Top parts makers like Bosch, Denso might each have a few percent of global aftermarket parts revenue, given their scale.
• Top distributors/retailers (GPC, AutoZone, LKQ) similarly each maybe hold 1-2% of global aftermarket revenue (but in their home regions they hold significant share; e.g., AutoZone and O’Reilly together have ~half the U.S. retail DIY market).
• Tire industry is more concentrated: top 5 tire makers have a majority of the tire market, which itself is ~10-15% of total aftermarket by value, so indirectly they have a noticeable chunk.
• The competitive landscape is thus one of oligopolies in some niches and fragmentation in others. For example, spark plugs: essentially NGK, Denso, Bosch dominate worldwide. Filters: many players but a few big ones (Mann+Hummel, Mahle, Fram). Brake parts: very fragmented with dozens of brands. So each segment has its own leaders.

Looking forward, competition may intensify with new entrants:

• Tech companies and startups aiming to service connected cars or sell parts subscription models.
• Automakers themselves possibly selling parts on their websites directly or rolling out mobile service for their brands (Tesla does this already since they don’t have franchised dealers).
• Consolidation continuing: We may see, for instance, further mergers among the big U.S. retailers or European distributors, creating even larger entities with global reach.

To conclude this section, the automotive aftermarket’s competitive landscape is characterized by a mix of long-established firms and agile newcomers. The major players have built their positions over decades and often have extensive infrastructure (factories, warehouses, store networks) that provide a moat. However, innovation and customer service remain key – an upstart with a new way to solve a problem (like predictive analytics to tell you when to change a part) could carve out a niche. As vehicles and consumer expectations change, the companies that adapt – through technology adoption, strategic partnerships, and maintaining quality – will solidify or improve their competitive standing.

The global automotive aftermarket has shown resilient growth in the past five years (–) and is poised for continued expansion through . Below, we present key data and trends regarding market size and forecasts:

Global Market Size: In , the global automotive aftermarket (parts and services combined for all vehicle types) is estimated to be over $1.8 trillion . This figure encompasses everything from oil changes in the US to tire sales in Asia and truck repairs in Europe. It highlights that the aftermarket is a trillion-dollar-plus industry worldwide. Different sources sometimes report different sizes depending on scope – for instance, some might count only light-duty vehicles or only parts (excluding labor). To clarify:

• Parts-only perspective: The global aftermarket for replacement parts (excluding service labor) was about $470–500 billion in . One projection put it at $499.4B in , rising to ~$642B by . Another by Grand View Research estimated $468.9B in with ~3.8% CAGR to .
• Combined parts & service perspective: Using the $1.8T as a baseline around and modest growth, the total global aftermarket (parts + labor) could reach roughly $2.2–2.5 trillion by . McKinsey’s analysis projected an increase from ~€800B in to ~€1.2 trillion by , which in dollar terms (assuming ~1.1 USD/EUR) aligns with ~$1.3T in to ~$1.5–1.6T in for light vehicles. Including heavy vehicles and inflation, $2T+ by is plausible.

These numbers underscore that the aftermarket constitutes roughly half or more of the entire automotive industry’s value creation (new car sales globally are on the order of $2T as well). It’s a massive opportunity space.

Regional Breakdown (-): The largest markets by value are North America (~30% of global), Europe (~25%), and China (~15% and rapidly growing), with the rest of Asia-Pacific, Latin America, and Middle East/Africa making up the remainder . In :

• The U.S. aftermarket was about $324B (parts & labor for light-duty) and grew to $338B in , expected to continue growing to ~$372B by (Statista projection).
• Europe’s light-duty aftermarket was around $250B in and should approach $270B by mid-decade (growth is slower, some of that is price inflation).
• China’s aftermarket was roughly $100B+ in and growing at high single digits or low double digits annually (some estimates show China crossing $150B by ).
• Other Asia (India, ASEAN, Japan, etc.) collectively perhaps $100B in , growing faster than mature markets.

Impact of Pandemic: The year saw a contraction in aftermarket revenue in many countries due to lockdowns (fewer miles driven, temporary shop closures). For example, U.S. aftermarket size fell a few percentage points in . Europe saw similar dips. However, and especially saw strong rebound growth, not only recovering the lost ground but exceeding pre-pandemic levels . This was driven by:

• Deferred maintenance coming due (vehicles that skipped service in needed it in ).
• A boom in used car usage (people bought used cars when new supply was tight, and invested in repairs).
• Price inflation for parts (raw material costs went up, raising part prices and hence market value).

Thus, the 5-year trend (–) is a dip and recovery to a higher trajectory. By , most markets are expected to be on normal growth tracks.

CAGR (–): Forecasts generally put global aftermarket growth at around 3% annually through . Some sources say 3.5% or 4% depending on segments . Breaking it down:

• North America: ~2–3% annual growth (slower volume growth, mainly inflationary or mix-driven).
• Europe: ~1–2% (very low volume growth, aging population and EVs could even flatten it, but Eastern Europe could boost the average).
• China: though percentage growth will decelerate (it was >10% a decade ago, but as market matures it might be ~5–6% going forward), China remains the largest contributor to absolute growth.
• Rest of Asia: 4–6% CAGR expected (India possibly higher around 8%, Southeast Asia in mid-single digits).
• Latin America & MEA: somewhat volatile, but likely 3–5% (these regions depend on economic cycles and exchange rates; e.g., Brazil’s aftermarket can swing with its economy).

Projections through : By , the global landscape may look like:

• North America aftermarket around $400–450B (light vehicles) plus heavy-duty ~$100B, totaling perhaps $500–550B.
• Europe (including Eastern) around $350–400B total.
• China alone possibly $300–400B (as per McKinsey ~€430B ~ $480B including service by , though EV adoption could trim that).
• Rest of Asia-Pacific (Japan, India, etc.) combined could be $200–300B.
• Rest of world (Latin America, Africa, Middle East) maybe $100–150B.

These are ballpark figures, but they align with the idea that Asia-Pacific will rival or exceed the combined NA and Europe by in aftermarket value.

Segment Outlooks:

• By product category, some shifts by : Tires and wear parts remain strong; expect EV-related parts and services (battery check/replace, electric motor service, coolant for battery systems, etc.) to emerge as a small but growing segment. Electronics (sensors, ECUs) replacements will rise in share as cars age with those components.
• By channel, e-commerce likely grabs a larger share of parts sales (possibly 20%+ of parts volume online by in some markets, up from low teens today). Traditional channels will still be significant but integrated with digital.
• Customers, the DIY portion may gradually shrink as cars get more complex, but a counter-trend is more do-it-for-me at non-dealer locations (since independent chains are expanding convenient services). Fleet share of aftermarket spend will increase if mobility trends continue (one analysis suggested more B2B and fleet business as a portion of aftermarket by ).

Key Drivers for –:

• Vehicle Miles Traveled (VMT): If VMT grows (from economic growth or more e-commerce delivery vehicles, etc.), it boosts wear-and-tear. VMT in developed countries is fairly flat per capita, but developing nations’ total VMT is increasing.
• Economic Conditions: A potential recession could cause slight dips (people delay non-critical fixes), whereas prosperity can increase discretionary accessory sales.
• New Vehicle Technology: As mentioned, more EVs and reliable technology could reduce some maintenance needs. Counteracting forces include increasing average age and more vehicles out of warranty.
• Regulations: Stricter environmental laws might require more frequent part replacements or new categories (e.g., in EU new regulations might require replacing older car parts to meet low-emission zones standards, or scrappage incentives could remove some older cars from the parc, which actually could shrink aftermarket a bit).
• Macro Risks: Supply chain issues (as seen recently) can temporarily inflate prices (increasing market value) or cause part unavailability (possibly shifting demand timing). Another pandemic or similar disruptive event could again cause temporary declines in driving.

In quantitative terms, one source (Fortune Business Insights) projects the global aftermarket to grow from ~$430.5B in to ~$568B by for parts – that’s a ~3.5% CAGR for parts. For the combined market, a 3% CAGR on ~$1.8T would yield ~$2.3T in .

To illustrate the growth, consider the global aftermarket value trend (including all segments, in nominal USD):

• (pre-COVID): roughly $1.5–1.6 trillion.
• : slight dip to ~$1.4–1.5T (lockdowns).
• : recovery to ~$1.6T.
• : jump to ~$1.7+T (catch-up demand, inflation).
• : ~$1.8T.
• (forecast): ~$1.95–2.0T (cumulative effect of growth).
• (forecast): ~$2.3–2.4T (with Asia-Pacific contributing an increasing slice of that).

Conclusion of Outlook: The automotive aftermarket is set to grow in absolute terms through , though the growth rates will be moderate in comparison to the boom times of the past in some regions. The profit pools will shift slightly – possibly narrowing for traditional players who don’t adapt (due to new competition and changing vehicle needs) but expanding for those who tap into emerging opportunities (EV maintenance, advanced diagnostics, digital service delivery). By , we expect a more digitally integrated aftermarket, servicing a larger and older global vehicle fleet that includes a mix of ICE and electric vehicles. Companies that invest now in understanding these trends – whether it’s stocking EV parts or integrating online sales – will be well-positioned in this high-value industry. The enduring fact is that as long as vehicles are on the road, there will be a need for replacement parts and services, ensuring that the automotive aftermarket remains a critical and robust sector of the global economy .

Aftermarket parts are components for your vehicle made and sold by a company other than your automaker. These parts can range from small things like windshield wiper blade inserts to critically important engine components. Aftermarket parts are used in vehicle maintenance, in body repairs after an accident, to repair your vehicle in the event of a breakdown, and as a way to improve the look or performance of your vehicle.

When your crossover, SUV, truck or car breaks down or is involved in an accident, you want the vehicle to be made right again. One concern many vehicle owners have is that the parts used in the repair will be substandard. In this context, aftermarket parts is a term that conveys a suspicion that the part is sub-par. By contrast, many vehicle owners who want to increase the performance or look of their vehicle opt for parts that they feel are clearly superior to the parts originally chosen by the manufacturer. Our point is that the term “aftermarket part” need not always have a negative connotation.

What are Aftermarket Parts

In a general context, an aftermarket part is one that you don’t purchase directly from your automaker’s authorized dealership or retail network. We wish we could extend the definition to be more all-encompassing, but the fact is, many parts one buys from a dealer that are considered “original equipment manufacturer” parts, a.k.a. “OEM” parts, are clearly labeled as having been made by another company other than your automaker. In other cases, the part is “private labeled,” meaning the automaker’s brand is applied to the part, but that part may also be used by other automakers, or perhaps even sold directly to the consumer by that parts supplier.

The most important aspect of any part is that it meets the demands of its application. The automaker, also called the “OEM,” goes to great lengths to select or design parts it feels meet the required budget (often the very first consideration), desired life expectancy, manufacturability, and aesthetics in some cases. Aftermarket parts are no different in this regard.

The fuzzy area in this conversation comes from the fact that automakers don’t actually make many of the parts you will someday replace. They use suppliers to make everything from belts and hoses, filters of all types, pumps, starters, suspension components, brake components (often stamped with the part maker’s name proudly on the outside of the caliper), infotainment systems, and pretty much everything else. Honda does not have a wheel bearing factory operated by Honda employees using raw materials made in Honda factories. It buys wheel bearings from a bearing manufacturer (usually a company called NTN), who itself uses multiple key suppliers in the creation of that wheel bearing.

Many of the parts that OEMs use are made by suppliers who also sell replacement parts or even upgrades directly to the consumer. In other cases, the aftermarket parts provider is a massive company making parts for thousands of individual applications. The idea that aftermarket parts are made by a shady fly-by-night operation someplace in a part of the world seen as less desirable is no longer valid, if it ever was.

What's the Difference Between Aftermarket and OEM Parts

The way that an OEM part is different from an aftermarket part is that the automotive manufacturer played a role in its design and selection, and perhaps its manufacturing. Following this participation, the manufacturer assigned that component a part number of its own and set up a distribution network to sell it or use it in dealer repairs. All of this comes at a very high cost to the consumer.

Aftermarket parts, by contrast, are engineered, tested, and manufactured to serve the same purpose as the original part. They are then marketed by the parts manufacturer, or a retail company. One part sold by an aftermarket supplier, let’s call them Acme, may in fact be made by multiple parts manufacturers to Acme’s specifications. And those specifications are very likely identical in all meaningful ways to the original automaker’s. Part of Acme’s overall business may include making OEM parts that they supply to automakers who call them their own.

Quality control is an important part of any manufacturing process. If there is any evidence that automotive manufacturers have superior quality control by comparison to the parts suppliers who make and market aftermarket parts, it’s hard to understand how that could be true. Let’s remember that OEMs often make mistakes. There were 53 million vehicles recalled in the U.S. in alone. Almost all of those recalls involved the failure of an OEM part that the automaker designed, specified, and took responsibility for the quality of.

Here is a great example. Toyota, Honda, Mazda, Subaru, and other manufacturers are presently struggling with a recall related to failing fuel pumps in their top-selling models. The reason that there is more than one manufacturer involved here is that these manufacturers didn’t make this critically important component. A huge parts manufacturer named Denso made the part they all shared and all applied their own “OEM” part number to. It gets better. Denso used to be owned by Toyota. Now only 25% of the company is owned by Toyota and Denso supplies components to multiple brands of automobiles. Is Denso in actuality then considered an OEM in their own right? The line is often blurred.

If you need another example of an “OEM” part failing and causing a major market disruption, search for “Takata airbag recall” in your browser. This component manufacturer supplied most major brands with OEM airbag inflators. OEMs don’t actually make that critical safety component. When it all went wrong, the OEMs didn’t call the failed part their airbag inflator. Instead, they pointed the finger at the supplier. It became the “Takata airbag recall.”

The point is, automakers want you to think their parts are superior to aftermarket parts. But when their “own parts” fail, they sometimes point at the supplier and name them as the cause.

Aftermarket Parts Pros and Cons

How Do Aftermarket Parts Work

If you have your vehicle serviced at the brand’s authorized dealer, you would assume that only original parts made by your automaker will be used in its maintenance or repair. Of course, this is not true. The single most expensive maintenance item on any vehicle is tires. And no automaker manufacturers tires. They don’t even bother to private label them. There are no “Ford SuperRound” tires or “Volkswagen GreatTread” tires. The OEMs buy the same tires from the same companies you do.

Oil is the lifeblood of the modern gasoline-powered vehicle. When you have the oil changed, the oil the dealer puts in is not made by the automaker, though it may well be available at the parts counter in a bottle labeled with the brand’s name and logo. Thus, the two most common and likely most costly components you will change in your vehicle are aftermarket parts, and are openly sold by your automaker inside their own dealerships.

Should you need a replacement alternator, the one the dealer installed may not be the same part number that the brand originally specified. We recently had an original alternator fail in our Subaru Forester. The folks at the Subaru dealership covered the replacement at no cost. Interestingly, the dealer didn’t use the original OEM alternator because the original OEM part was found to have a lifespan of just a few years and was causing trouble with the engine’s performance before it would ultimately fail. As you can see, original parts are sometimes even substituted by the automakers themselves.

One part you will almost certainly change before your vehicle turns five years of age is the 12-volt battery. This is true even if you own an electric vehicle. In the United States, two companies dominate the 12-volt battery business, Johnson Controls, Inc. and Exide Technologies. If you buy a replacement battery from your car dealership it may well have the name of the car brand on it, but they didn’t make it. It was made in the same factory that built all of the aftermarket batteries you could have bought for less from AAA, a local auto parts store, or have installed by a local mechanic.

Aftermarket parts like an oil filter, alternator, starter, AC compressor, wheel bearing, brake rotor, or other commonly-replaced parts are typically the first choice of independent repair shops. These shops know and trust various aftermarket brands because they use them every day to make affordable repairs on cars owned by lifelong customers. These shops know which brands make a quality part for that specific repair. Most importantly, they know that in many cases, the aftermarket parts perform as well or better than the OEM parts that they could source and this will save money for their customers. No shop wants to use a part that will have a distraught customer come back a week later with a car on a flatbed. Don’t assume aftermarket parts used by your trusted local shop are of low quality.

Most of our overview thus far has centered around late-model vehicles and their parts. It’s important to be mindful of the fact that OEM parts for older cars may no longer be available. In many cases, parts with superior performance made by aftermarket suppliers replaced the original part somewhere along the timeline of that model’s existence.

One thing to keep in mind whenever one is purchasing an aftermarket part to repair a vehicle is that the OEM part failed. Had it not failed, the replacement part would not be needed. If you are a fan of the show Wheeler Dealers you may have noticed that many of the problems with the vehicles the show returns to good condition are often solved by the substitution of an aftermarket part that works better than the OEM part did.
