There isn’t a single oil filter number that fits every WRX; the correct part depends on the model year and engine code. For many EJ-series WRX models, the OEM filter commonly cited is 15208AA12A.
Why the WRX oil filter number varies
The WRX line has used several different engines over its history. Early generations relied on the EJ20/ EJ25 turbo engines, while newer models use the FA-series turbo engines. Each engine family may use a different filter design and part number. The exact number is best confirmed by the engine code, year, and a parts diagram or dealer lookup.
How to identify the correct filter for your car
Use a reliable verification method to avoid ordering the wrong part. Here are steps you can take:
- Check your vehicle’s engine code and year. 2002–2014 WRXs typically featured EJ-series turbo engines, while 2015+ WRXs use the FA-series turbo engines.
- Refer to the official Subaru parts catalog for your exact model, or ask a Subaru dealer using your VIN to pull the correct oil filter number.
- Inspect the filter you remove; many OEM Subaru filters have the part number printed on the side or end of the can.
Following these steps ensures you get the correct filter in the right size and with the proper thread size for your WRX.
Common quick-reference guidance
As a general guide, engineers and parts catalogs commonly cite 15208AA12A as the typical OEM filter for many EJ-series WRX engines, with variations possible for different engine families and model years. Always verify against official documentation or your existing filter.
What to do if you’re unsure
If you’re unsure or don’t have access to the parts catalog, contact a Subaru dealership or a trusted independent shop. Provide your VIN, model year, and whether your WRX uses the EJ or FA engine, and they can confirm the exact part number for you.
Summary
There isn’t a universal WRX oil filter number. The correct part depends on the engine code and year. The 15208AA12A OEM filter is a common reference for many EJ-series WRXs, but you should verify with the exact model and engine type via the Subaru parts catalog or dealer. Always check the filter itself if possible and use your VIN to confirm the correct number.
