In brief: there isn’t a single universal oil filter part number for every Crosstrek; the exact number varies by year and engine variant. This article explains how to identify the correct filter for your car and what numbers you may encounter.
For most Crosstrek models, the 2.0-liter flat-four engine is standard across generations, but Subaru has used a few related filter part numbers over time. To ensure you buy the right filter, identify your engine code and year, then cross-check Subaru’s official parts catalogs or the markings on your current filter.
Why the number varies by model year and engine
The Crosstrek has evolved through multiple generations, with occasional changes to the engine family and the filter mounting. Because of these updates, the same-looking filter can carry different part numbers in different years. Verifying your engine code or VIN helps you avoid ordering the wrong part.
How to identify the exact oil filter for your Crosstrek
The following steps guide you to the precise part number before purchasing a replacement.
- Check your Crosstrek’s engine code and model year. The 2.0-liter flat-four is common, but the specific filter requirement can differ by code family and revision.
- Inspect the oil filter currently installed on your vehicle. The OEM part number is often printed on the side of the filter canister or on the filter label.
- Use Subaru’s official parts catalog or a reputable retailer. Enter your VIN or engine code to pull the exact OEM filter match for your vehicle.
- When in doubt, contact a dealer or trusted shop and provide your VIN. They can confirm the correct part number for the exact year and configuration.
By following these steps, you’ll be more confident in selecting the correct filter and maintaining proper oil filtration for your Crosstrek.
Common numbers you may encounter
In practice, several 2.0L Crosstrek engines share a closely related family of filter numbers. The most frequently cited OEM part number for many Crosstrek 2.0L models is 15208AA12A, with related variants used for other years or updated filter designs. Always verify against your specific vehicle to be sure.
Notes on verifying the right part
Because variations exist between generations and regional models, relying on the exact engine code (e.g., FB20/FA20 family) and your VIN is the safest path to the correct number. When purchasing online, input your VIN to ensure compatibility.
Summary
The oil filter part number for a Subaru Crosstrek is not universal; it depends on the year and engine variant. Start by identifying the engine code or VIN, check the current filter for the exact label, and consult Subaru’s official parts listings or a trusted retailer to confirm the correct OEM number. For many 2.0L Crosstrek engines, 15208AA12A is a common reference, but variations exist—always verify before purchasing.
