Volkswagen Passat (2006-2010): B6 PQ46 Platform Fitment Guide for North America

Written by Arthur Simitian | PartsAdvisory

The Volkswagen Passat sold in North America from 2006 through 2010 is the B6 generation, internally designated Typ 3C and built on the PQ46 platform. It was introduced at the Geneva Motor Show in March 2005 and arrived in North American dealerships as a 2006 model year sedan, with the wagon following mid-year. The B6 replaced the B5.5 and represents the second time in the Passat's North American history that the platform architecture reversed from the preceding generation. Where the B5 had returned to a longitudinal engine layout shared with the Audi A4, the B6 reverted to a transverse layout, this time on a long-wheelbase development of the PQ35 platform shared with the Golf Mk5 and Jetta Mk5. This architectural reversal carries the same catalog consequence it always has: no drivetrain, engine, or transmission component from the B5.5 crosses to the B6, and no B6 component applies to the B5.5.

The North American B6 window is five model years long but unusually eventful in catalog terms. The wagon arrived mid-year in 2006. The 3.6 VR6 was available from 2006 through 2008 in the United States and was discontinued for 2009. The 4motion all-wheel-drive option was tied exclusively to the VR6 and was discontinued at the same time. The 2.0T engine changed from the BPY FSI specification to the CBFA TSI specification during the 2009 model year. The manual transmission was discontinued after 2008. The conventional six-speed automatic was replaced by the six-speed DSG dual-clutch unit for the 2010 model year. By the end of the B6 window in 2010, the lineup had contracted to a single Komfort trim, a single 2.0T engine, front-wheel drive only, and the DSG as the only transmission, making the 2010 application the simplest single-year Passat catalog entry in the entire series covered by these guides.

This guide addresses the United States market throughout. Canadian applications carried the VR6 and 4motion through the 2010 model year, creating a market split in the 2009 and 2010 entries that must be handled by confirming market before assigning drivetrain and engine components.

Platform: PQ46, Transverse Layout, and the Break from PL45

The B6 is built on the PQ46 platform, a development of the PQ35 platform used by the Golf Mk5 and Jetta Mk5, extended to accommodate the Passat's larger body. The platform uses a transverse engine layout, returning to the orientation used in the B3 and B4 Passat generations after the B5's longitudinal detour. The transverse layout is the defining architectural fact for catalog work on the B6 because it governs the entire drivetrain orientation, accessory drive geometry, and transmission family, all of which share nothing with the longitudinal PL45 platform of the B5.5.

The PQ46 platform carries an independent four-link front suspension and a semi-independent torsion beam rear axle on front-wheel-drive models. The 4motion all-wheel-drive variant uses the Haldex multi-plate clutch system rather than the Torsen centre differential of the B5.5. The Haldex system is a reactive design that operates as a front-wheel-drive vehicle until slip is detected, at which point torque is distributed rearward through the clutch pack. This is architecturally different from the Torsen-based permanent AWD of the B5.5, and no AWD drivetrain component crosses between the two generations. The rear suspension on 4motion models is a fully independent multilink setup to accommodate the rear differential and halfshafts, as in the B5.5, but the specific geometry, mounting points, and component specifications are generation-specific.

The PQ46 platform shares front suspension geometry and some front brake architecture with the Golf Mk5, Jetta Mk5, and related PQ35-derived applications. Front strut components, front wheel bearings, and front brake rotors and calipers cross between the B6 Passat and the Golf Mk5 and Jetta Mk5 at matching engine and equipment specifications. This is a narrower and more precisely bounded cross-reference family than the B5's Audi A4 connection, and it should be treated as a cross-reference to confirm rather than assume.

The B6 body is 9.2 centimetres longer and 7.4 centimetres wider than the B5.5, representing a significant dimensional growth. This means no exterior body panel, door, or glass from the B5.5 crosses to the B6. The wheelbase of 2,709 mm (approximately 106.7 inches) is virtually unchanged from the B5.5's 2,708 mm, but the overall body dimensions are different enough that door glass, windscreen, and rear glass must be confirmed as B6-specific before any cross-reference to the B5.5 is applied.

Naming and Trim Structure: A New System for the B6

The B6 abandoned the GL, GLS, and GLX trim nomenclature used throughout the B5 and B5.5 window and adopted a system that named trims after the engine or equipment level. The 2006 lineup used Value Edition, 2.0T, 3.6, and 3.6 4Motion designations. Later years simplified and consolidated these into Turbo, Lux, and VR6-based names before contracting to a single Komfort trim by 2009. This naming change has no impact on mechanical catalog work but does affect trim-level feature listings and equipment-level component assignments such as wheel size, seat specification, and audio system hardware.

The transition from named trims to engine-designation trims also created a situation in some catalog systems where the older GL, GLS, and GLX codes were carried forward as defaults. Any catalog that assigns B6 applications using B5-era trim designations is applying the wrong trim framework to the B6 generation.

North American Lineup Year by Year: 2006 Through 2010

2006: Sedan at Launch, Wagon Mid-Year, 2.0T and 3.6 VR6

The B6 launched in the United States for the 2006 model year in sedan body style only, with the wagon arriving mid-year. Sedan-only catalog entries for 2006 are correct for the early portion of the model year; wagon applications must confirm mid-year availability before any rear body component listing is assigned to a 2006 wagon.

Two engines were available: the 2.0-litre turbocharged four-cylinder producing 200 hp, designated 2.0T and using the BPY engine code with Fuel Stratified Injection; and the 3.6-litre VR6 FSI producing 280 hp, designated 3.6 or 3.6 4Motion and using the BLV engine code. The 2.0T was available with a six-speed manual or a six-speed conventional automatic (09G). The 3.6 VR6 was available only with the six-speed conventional automatic (09M) and was available with or without 4motion. No manual transmission was offered with the VR6 in North America.

The 09G and 09M are both Aisin TF-60SN-based six-speed conventional automatics. They are not interchangeable. The 09M carries modifications to handle the VR6's greater torque output, and its transmission pan and fluid filter differ dimensionally from the 09G. A transmission component listed for the 09G 2.0T application must not be applied to the 09M VR6 application.

The 3.6 VR6 in the 2006 and 2007 North American Passat uses a one-piece variable-length intake manifold with a vacuum-actuated flapper that improves mid-range torque. From 2008 production onward, the VR6 received a simplified two-piece fixed-length intake manifold. These are different physical assemblies; a 2006 or 2007 VR6 intake manifold listing does not cross to a 2008 VR6 application.

2007: Wagon Full Year, Twelve-Way Power Seats Added

For 2007 the wagon was available for the full model year in both 2.0T and 3.6 configurations. Twelve-way power front seats became available, and an auxiliary input was added to the audio system. No mechanical changes distinguished 2007 from 2006 at the platform or powertrain level. Components confirmed for the 2006 application cross to 2007 within matching engine and drivetrain specifications.

2008: VR6 Front-Drive Sedan Added, Manual Still Available

For 2008 a new front-wheel-drive VR6 sedan was introduced in addition to the continuing 4motion VR6 sedan and wagon. This created a VR6 FWD sedan application that had not existed in 2006 or 2007. The VR6 FWD sedan uses the same 09M transmission as the VR6 4motion but without the Haldex rear differential. Rear suspension on the VR6 FWD sedan reverts to the torsion beam used on FWD 2.0T models. A VR6 FWD sedan rear suspension listing must confirm FWD architecture rather than defaulting to the multilink rear of the VR6 4motion.

The VR6 intake manifold changed from the one-piece variable-length design to the two-piece fixed-length design for 2008 as noted above. This is the most practically significant mechanical distinction within the VR6 application across the 2006-2008 window.

The manual transmission continued to be available on 2.0T models for 2008. The VR6 remained automatic-only. The 12-way power driver seat became standard across the lineup.

2009: VR6 Discontinued, 4motion Discontinued, Manual Discontinued, Single Komfort Trim

The 2009 model year is the most consequential catalog boundary within the B6 North American window. Three things were discontinued simultaneously: the 3.6 VR6 engine, the 4motion all-wheel-drive system, and the manual transmission. The lineup contracted to a single Komfort trim available in sedan and wagon, powered by the 2.0T in front-wheel drive only, with the six-speed conventional automatic as the only transmission. In the same model year, paddle shifters were added to the steering wheel as standard.

This means that no VR6 application, no 4motion drivetrain application, and no manual transmission application exists for the 2009 or 2010 United States Passat. A catalog that carries VR6, 4motion, or manual transmission listings into 2009 or 2010 is assigning powertrains and drivetrains that were not sold in those model years in the United States.

In Canada, the VR6 and 4motion continued through 2010. A 2009 or 2010 Canadian B6 Passat may legitimately carry the VR6 and 4motion. Any catalog entry that assigns VR6 or 4motion components to a 2009 or 2010 Passat must confirm the Canadian market before doing so.

The 2.0T engine in the 2009 model year also changed specification. The BPY FSI engine was replaced by the CBFA TSI engine. Both displace 2.0 litres and both produce 200 hp in North American specification, but they are different engine codes with different fuel injection system architecture. The BPY uses Fuel Stratified Injection, a port-and-direct combined approach. The CBFA is a direct-injection TSI unit from the EA888 Gen1 family. Fuel system components, high-pressure fuel pump specification, injector design, and engine management software differ between the two. A fuel system component confirmed for the BPY does not cross to the CBFA. The transition from BPY to CBFA occurred during the 2009 production run, not at a clean annual boundary. Build date confirmation is required for 2009 model year 2.0T engine management and fuel system components.

2010: DSG Replaces Conventional Automatic, Final B6 Year

For 2010 the six-speed conventional automatic was replaced by the six-speed DSG dual-clutch transmission as the sole automatic option. No conventional automatic was available in 2010. The DSG in the 2010 Passat is the DQ250 six-speed wet-clutch dual-clutch unit, designated 02E in VW internal coding. The 02E DSG is architecturally different from the 09G conventional automatic it replaced. Internal components, fluid specification, filter hardware, and mechatronic module are all DSG-specific and do not cross to the conventional automatic. A transmission pan or filter confirmed for the 09G conventional automatic does not fit the 02E DSG, and vice versa.

The 2010 model year also added Bluetooth as standard equipment and a redesigned multifunction steering wheel. No mechanical changes beyond the transmission occurred in the 2010 model year.

The B6 was replaced in the United States by the Passat NMS, built at Volkswagen's Chattanooga, Tennessee facility, beginning with the 2012 model year. The NMS is a longer, wider vehicle on a different platform developed specifically for the North American market and shares no body, exterior, or drivetrain components with the B6 Passat.

Engines: 2.0T and 3.6 VR6, Two Distinct Families

2.0-Litre Turbocharged Four-Cylinder (2.0T)

The 2.0-litre turbocharged four-cylinder is the only engine offered for all five model years of the North American B6 window. It produces 200 hp and 207 lb-ft of torque throughout. Despite this apparent consistency, the engine underwent a code and architecture change during the 2009 model year that creates a catalog boundary within the 2.0T application.

From 2006 through the early part of the 2009 model year, the 2.0T uses the BPY engine code from the EA113 engine family, with Fuel Stratified Injection. This engine is shared with the Golf GTI, the Jetta GLI, and other VW Group applications using the EA113 2.0T in transverse mounting during the same period. Engine service components including timing belt, water pump, spark plugs, oil filter, and air filter cross between the B6 Passat BPY and these related applications within matching specifications.

From the 2009 model year onward, the 2.0T uses the CBFA engine code from the EA888 Gen1 family, a direct-injection TSI design introduced in February 2008 in European markets and arriving in North American production during 2009. The CBFA uses a timing chain rather than a timing belt. This is the most functionally significant service difference between the BPY and CBFA: the BPY requires periodic timing belt replacement as an interference engine, while the CBFA uses a timing chain that does not have a scheduled replacement interval in the same sense. A timing belt kit listed for the BPY application must not be applied to the CBFA, and a CBFA chain tensioner component does not apply to the BPY. Any timing drive service component listing for the 2.0T must confirm the engine code before the specification is assigned.

The CBFA's high-pressure direct injection fuel pump is also different from the BPY's fuel system. The CBFA uses a cam-driven high-pressure fuel pump that delivers fuel directly to the injectors at high pressure. The BPY's Fuel Stratified Injection combines port injection with direct injection at a different pressure architecture. Fuel pump, fuel injectors, and fuel rail components are engine-code-specific and must not be cross-referenced between BPY and CBFA.

The 2.0T manual transmission in the 2006 through 2008 model years uses the six-speed 02Q manual gearbox in its long-ratio specification. This is the same family as the six-speed manual in the Golf GTI and Jetta GLI of the same period. Clutch, flywheel, and gearbox internal components cross between these applications within matching specifications.

3.6-Litre VR6 FSI (2006 Through 2008 United States, 2006 Through 2010 Canada)

The 3.6-litre VR6 FSI in the B6 Passat carries the BLV engine code and produces 280 hp. This is a 24-valve direct-injection VR6 using the EA390 engine family. It is fundamentally different from the 30-valve conventional V6 of the B5.5 in every respect: different cylinder angle, different injection system, different valve train architecture, and different engine management. No engine internal component crosses between the B6 3.6 VR6 and the B5.5 2.8 V6.

Within the B6 window, the VR6 carries two significant production-run distinctions. First, the intake manifold changed from the one-piece variable-length design on 2006 and 2007 production to the two-piece fixed-length design on 2008 production. Second, early 2006 and 2007 VR6 engines have a documented oil pump drive sprocket bolt that could back out due to inadequate installation torque from the factory. This bolt engages the timing chain, and its failure can cause the chain to skip timing and produce catastrophic engine damage. The issue was corrected in late 2007 production. Any oil pump drive sprocket or timing chain listing for the 2006 or early 2007 VR6 should note the oil pump bolt as a required inspection point.

The 3.6 VR6 FSI uses the 09M conventional automatic in North America throughout its production run. No manual transmission, no DSG, and no other automatic variant was offered with the VR6 in the North American B6 Passat. The 09M carries a larger transmission fluid filter on 4motion wagon applications than on FWD or 4motion sedan applications. A transmission fluid filter listing for the VR6 must confirm body style and drivetrain before the filter size specification is applied.

The VR6 engine service components do not broadly cross to the Golf Mk5 or Jetta Mk5, because neither of those vehicles used the 3.6L FSI VR6. The 3.5-litre and 3.2-litre VR6 engines in other VW Group applications of the period share some accessories and exhaust hardware with the BLV, but internal engine components, head design, and direct injection hardware are specific to the 3.6 FSI architecture. Cross-references to other VR6 applications require individual component confirmation rather than platform-level assumption.

Drivetrain Splits: FWD vs 4motion

The 4motion all-wheel-drive system was available exclusively with the 3.6 VR6 in the North American B6 Passat. No 2.0T 4motion application was sold in the United States for any year of the B6 window. This is a tighter restriction than the B5.5 window, in which 4motion eventually became available with the 1.8T. Any 4motion rear drivetrain component assigned to a 2.0T B6 Passat application is assigning hardware to a vehicle that never had AWD.

The 4motion rear suspension on the B6 uses a fully independent multilink rear axle to accommodate the rear differential and Haldex coupling, replacing the torsion beam rear of FWD models. As in every previous generation with both FWD and AWD variants, rear shock absorbers, rear springs, rear wheel bearings, and rear axle geometry components are architecture-specific and do not cross between FWD torsion beam and 4motion multilink applications. A rear spring confirmed for an FWD 2.0T Passat will not fit the 4motion rear suspension mount geometry.

The Haldex unit on the B6 4motion requires its own fluid service separate from the rear differential. Haldex filter, Haldex fluid, and rear differential fluid are separate service items that do not cross to each other and do not apply to FWD applications. The Haldex unit on the B6 is the fourth-generation Haldex design and is specific to PQ-platform transverse applications. It does not share service components with the Torsen-based 4motion of the B5.5.

The 4motion VR6 was available in sedan and wagon configurations. The VR6 FWD sedan introduced for 2008 was not available as a wagon; all VR6 wagons in the United States were 4motion. A VR6 wagon rear suspension listing must default to the multilink 4motion architecture. A VR6 sedan rear suspension listing must confirm FWD or 4motion before the architecture is assigned.

Body Style: Sedan and Wagon

The four-door sedan and five-door station wagon share identical front body structure and all components forward of the B-pillar including front doors, front door glass, windscreen, hood, front fenders, headlamps, and front bumper. All front suspension components, front brake components, and engine service items cross freely between sedan and wagon within matching engine and drivetrain specifications.

Aft of the B-pillar the two body styles are entirely different. The wagon carries a longer roof section, different rear quarter panels, a rear liftgate with power operation on all but the most basic trims, different rear glass, different rear lamp clusters, and a different rear bumper. The wagon cargo area offers 35.8 cubic feet behind the rear seat, expanding to approximately 62 cubic feet with the rear seat folded. These are wagon-specific structural dimensions with no sedan equivalent.

The wagon rear door glass differs from the sedan rear quarter glass in both area and opening mechanism. The wagon rear liftgate and its glass assembly are wagon-specific with no sedan cross-reference. A taillamp cluster confirmed for the sedan does not cross to the wagon.

A power liftgate was standard on wagons across the B6 lineup. Liftgate actuator components, liftgate strut assemblies, and liftgate latch mechanisms are wagon-specific. No sedan-equivalent liftgate actuator listing applies.

Rear spring rates for FWD applications differ between the sedan and wagon. The wagon carries a higher rear spring rate to support its greater practical payload. Rear spring listings for FWD applications must confirm body style before the spring rate specification is assigned.

The wagon was not available at the beginning of the 2006 model year. Any 2006 wagon application must account for the mid-year introduction. Early model year 2006 production does not include wagon vehicles.

Transmission Summary Across the Window

The B6 window contains four distinct transmission applications that require separate catalog entries.

The six-speed manual 02Q was available on 2.0T models from 2006 through 2008. It was discontinued for 2009. A manual transmission listing for a 2009 or 2010 North American Passat is wrong.

The six-speed conventional automatic 09G was available on 2.0T models from 2006 through 2009. It was replaced by the DSG for 2010. A 09G conventional automatic listing for a 2010 Passat is wrong.

The six-speed conventional automatic 09M was available on 3.6 VR6 models from 2006 through 2008. It is a different unit from the 09G, with higher torque capacity and a different filter specification on 4motion wagon applications. A 09G component listing must not be applied to the 09M, and vice versa.

The six-speed DSG 02E was available on 2.0T models for the 2010 model year only within the United States B6 window. It is the sole transmission offered for 2010 and is architecturally different from all three conventional automatic and manual transmissions used earlier in the window. DSG mechatronic, DSG fluid, and DSG internal components do not cross to any conventional automatic application.

Cross-Reference Family: Golf Mk5, Jetta Mk5, and the PQ46 Platform

The PQ46 platform creates a cross-reference family with the Golf Mk5 and Jetta Mk5 at the front suspension and front brake level. Front strut cartridges, front springs, front control arms, front wheel bearings, and front brake rotors and calipers cross between the B6 Passat and Golf Mk5 and Jetta Mk5 within matching engine weight and equipment specifications. This cross-reference is confirmed at the platform level and represents the most reliable shared undercar component family for the B6 Passat.

For 2.0T engine service components, the BPY application crosses to the Golf GTI and Jetta GLI of the same period within the EA113 family. The CBFA application crosses to other EA888 Gen1 applications in the VW Group. These cross-references are engine-family-specific and must be confirmed by engine code rather than assumed by displacement and model year.

The B6 Passat does not share platform components with the B5.5 Passat in any meaningful category. The architectural difference between the PQ46 transverse platform and the PL45 longitudinal platform is a complete mechanical separation. Cross-references between B6 and B5.5 are limited to consumables that are not vehicle-specific.

Common ACES/PIES Catalog Mistakes

The first error is applying 3.6 VR6 or 4motion listings to 2009 or 2010 United States Passat applications. The VR6 was discontinued for the 2009 model year in the United States and 4motion was discontinued at the same time. No VR6 engine component, no 09M transmission component, and no Haldex or rear differential component applies to any 2009 or 2010 United States B6 Passat.

The second error is applying a single 2.0T fuel system listing to all B6 production without separating the BPY FSI from the CBFA TSI. The two engines share displacement and power output but use different injection architectures, different high-pressure pump designs, different injectors, and different timing drive systems. Fuel pump, injectors, and timing belt kit components confirmed for the BPY must not be applied to the CBFA.

The third error is applying a timing belt replacement schedule and components to a 2009 or later 2.0T CBFA application. The CBFA uses a timing chain, not a timing belt. A timing belt listing applied to a CBFA Passat is assigning a service component that does not exist on the vehicle.

The fourth error is applying a 09G conventional automatic pan or filter to a 09M VR6 application. The 09M carries a different filter than the 09G, and 4motion wagon applications of the 09M carry a larger filter than other 09M configurations. Transmission filter listings must confirm engine, drivetrain, and body style before the specification is assigned.

The fifth error is applying a conventional automatic transmission listing to a 2010 Passat. The 2010 model year uses the 02E DSG exclusively. A 09G pan, filter, or fluid listing assigned to a 2010 Passat is assigning components from a transmission that was not installed in that model year.

The sixth error is applying 4motion rear suspension or rear differential components to a 2.0T application. The 4motion system in the North American B6 was exclusively VR6. All 2.0T applications in the United States are front-wheel drive. Haldex filter, Haldex fluid, rear differential, rear multilink suspension components, and rear halfshafts do not apply to any United States B6 2.0T Passat.

The seventh error is treating the 2006 wagon as available for the full model year. The wagon arrived mid-year in 2006. Catalog entries covering early 2006 production must confirm body style against build date before assigning a wagon application.

The eighth error is applying a VR6 4motion wagon rear drivetrain listing to a VR6 FWD sedan application. The VR6 FWD sedan was introduced for 2008 and uses the torsion beam rear suspension of FWD models, not the multilink rear of the 4motion wagon. Rear suspension components from the 4motion wagon do not fit the FWD sedan rear suspension geometry.

The ninth error is applying a VR6 intake manifold listing without separating the 2006-2007 one-piece variable-length design from the 2008 two-piece fixed-length design. These are different physical assemblies with different vacuum circuit layouts. An intake manifold confirmed for 2006 or 2007 does not cross to 2008 production.

The tenth error is applying B5.5 Passat drivetrain, engine, or suspension components to B6 applications on the basis of shared Passat nameplate. The B5.5 uses the PL45 longitudinal platform with a Torsen 4motion system. The B6 uses the PQ46 transverse platform with a Haldex 4motion system. No drivetrain component, engine mount, transmission, suspension geometry component, or AWD hardware crosses between the two generations.

The eleventh error is applying 2009 or 2010 Canadian VR6 or 4motion specifications to United States applications for those years. In Canada the VR6 and 4motion continued through 2010. In the United States they were discontinued after 2008. Market confirmation is required before any 2009 or 2010 VR6 or 4motion listing is assigned.

The twelfth error is assigning the manual transmission to 2009 or 2010 applications. The manual was discontinued in the United States after the 2008 model year. A six-speed manual 02Q clutch, flywheel, or gearbox listing for a 2009 or 2010 Passat is assigning a drivetrain component that was not available in those years.

Front suspension and front brake cross-references to Golf Mk5 and Jetta Mk5 confirmed within matching engine weight and equipment level before cross-reference is published; B6 Passat does not share rear suspension cross-references with Golf Mk5 or Jetta Mk5 on FWD applications due to different rear load capacity.

Final Take

The 2006-2010 B6 Passat is a window defined by progressive simplification. The lineup began in 2006 with four trim levels, two engines, three transmission options, and AWD availability. By 2010 it had contracted to a single trim, one engine, one transmission, and front-wheel drive only. This progressive reduction creates an unusual catalog challenge where earlier years are more complex and later years are simpler, and where applying any discontinued option to the simplified later years generates wrong components.

The two most consequential year-specific boundaries are 2009 and 2010. The 2009 boundary removed the VR6, 4motion, and manual transmission simultaneously, making it the largest single-year reduction in any Passat generation covered by this series. The 2010 boundary replaced the conventional automatic with the DSG, a transmission architecture change that affects every automatic transmission service component. Both boundaries are clean annual cuts for the United States market, making them easier to apply than the mid-year production transitions in other generations, but they are also the boundaries most likely to be missed by a catalog that treats the full 2006-2010 window as a continuous application.

The 2.0T engine code change from BPY to CBFA during the 2009 model year is the subtler of the two boundaries and the one most likely to generate quiet errors over time. The power output is unchanged, the displacement is unchanged, and the external appearance of the engine is similar. Only the engine code confirms which family applies, and the timing drive system alone, belt versus chain, creates a fundamental service difference that makes the distinction unavoidable in practice.

Disclaimer

This guide is intended for catalog research, fitment analysis, and parts advisory reference. Production specifications, option availability, and regulatory compliance requirements vary by model year, regional market, and assembly date within any given window. Always confirm application data against vehicle identification number decoding, factory build sheets, and OEM parts documentation before finalizing a listing or parts recommendation. PartsAdvisory and its contributors are not responsible for fitment errors arising from catalog data that has not been independently verified against physical vehicle inspection or official OEM sources.
