Subaru Engine Oil Filter Kit 15208AA100 with 11126AA000 Crush Gaskets — 2-Pack OEM Fit for Legacy Outback Impreza WRX/STI Forester

This kit contains two Subaru factory oil filters (part 15208AA100) and two corresponding 21mm crush gaskets (part 11126AA000) designed to replace the factory-installed items during routine oil service. Subaru changed the external appearance of their oil filters as of 11/1/2022, so the unit you remove may differ visually from the one supplied here — but the internal filtration and fit meet Subaru’s specifications. The set is intended for vehicles listed below; some Legacy and Outback 2.5 models built 2010–2012 require a different crush washer (803916010), so verify your engine’s drain-plug diameter before ordering.

Which Subaru models will accept this 15208AA100 filter and 11126AA000 gasket kit?

The kit is compatible with a broad range of Subaru 4-cylinder and certain all-engine models produced across multiple years. Always cross-check the part numbers and your VIN or owner’s manual to confirm fitment before installing. If your vehicle requires the smaller crush washer noted above, do not use this kit.

• Outback 1996–2009 (4-cylinder engines only)
• Legacy 1990–2012 (4-cylinder engines only)
• Impreza 1993–2011 (non-turbo models)
• WRX & STI 2002–2014 and STI 2015–2021
• Forester 1998–2010 (all engines)
• Baja 2003–2006 (all engines)

How does a genuine Subaru oil filter kit benefit engine maintenance?

Using OEM filters and gaskets helps preserve factory tolerances, filtration performance, and proper drain-plug sealing during oil changes. Genuine components are designed to trap microscopic contaminants and avoid premature bypass, which supports oil longevity and consistent lubrication. They also simplify servicing because fit and thread engagement match Subaru factory parts.

• Engineered to Subaru specifications for flow and filtration
• Crush gasket sized to seal the drain plug and prevent leaks
• Supplied as a 2-pack to cover two service intervals or two vehicles
• Visual updates since 11/1/2022 do not change fit or function

What should I know before replacing my oil filter and crush gasket?

Check your owner’s manual for the recommended oil and filter change interval — commonly every six months or 7,500 miles depending on driving conditions — and inspect the drain-plug size first. If your Legacy or Outback 2.5 (2010–2012) uses the smaller crush washer (803916010), order that specific washer instead. Dispose of used filters responsibly and tighten the drain plug to the torque specified by Subaru.

• Confirm drain-plug diameter and required crush washer part number
• Observe recommended oil change intervals in the owner’s manual
• Torque drain plug to OEM specifications to avoid leaks or damage
• Keep the boxed filters clean until installation to prevent contamination

Are these filters identical to the ones originally installed by Subaru?

Functionally yes: these are Genuine Subaru parts made to match Subaru’s filter and gasket specifications. The exterior appearance of filters was updated in late 2022, so visual differences from your removed filter are possible, but filtration performance and fit remain OEM. Do not mix with aftermarket filters whose internal media or bypass characteristics may differ.

• OEM part numbers: filter 15208AA100 (formerly SOA6351520812) and gasket 11126AA000
• Manufactured to Subaru’s quality and fitment standards
• Sold as a set: two filters and two crush gaskets per package

Who this kit is for: Subaru owners or independent technicians who prefer genuine OEM components for routine oil service on compatible Legacy, Outback, Impreza, WRX/STI, Forester and Baja vehicles. This set suits drivers who want correct fitment, factory-level filtration, and a matched drain-plug gasket for leak-free oil changes. If you’re unsure about the crush washer size for your specific model year, consult your dealer or the vehicle’s service manual before purchase.
