Answer: There isn’t a single Fram oil filter number that fits all 2010 Subaru Forester models. Fram offers multiple part numbers that cross-reference to Subaru’s OEM filter, and the exact number depends on your engine variant and the Fram line you choose. The most reliable approach is to cross-reference Subaru’s OEM filter and confirm the exact Fram part with Fram’s catalog or a trusted retailer.
Engine variants in the 2010 Forester
Understanding which engine your Forester has is important because the correct Fram part number can differ between variants. The 2010 Forester was offered with more than one engine setup, and the filter must match the engine’s thread size, gasket diameter, and overall dimensions.
- 2.5-liter naturally aspirated four-cylinder engine (non-turbo)
- 2.5-liter turbocharged engine (XT trim)
These two configurations influence which Fram filter lines and specific part numbers align with the vehicle. Always confirm the exact fit for your trim level and engine code.
Fram lines and cross-reference for Subaru
Fram publishes cross-reference information so you can match Subaru’s OEM filter to a Fram part. Since the Forester’s engine options vary by year and trim, the right Fram number will depend on the cross-reference results for Subaru’s 15208-series filters. Use Fram’s cross-reference tools or consult a retailer to ensure you pick the correct model for your engine.
- Identify your engine code and model year to determine which Subaru OEM filter is installed (for the 2010 Forester this is commonly associated with the 15208-series filter).
- Compare the old filter’s specifications (thread size, gasket outer diameter, and overall height) with Fram’s listed specs to find compatible Fram part numbers.
- Use Fram’s official cross-reference tool or contact Fram/retail support to confirm the exact part number for your engine variant and trim.
- Confirm the chosen Fram filter at the point of purchase by providing your vehicle’s year, model, engine code, and trim to ensure a correct fit.
In practice, you’ll typically find multiple Fram options that cross-reference Subaru’s OEM filter, so verification is key to avoid selecting an incompatible model.
How to verify the part number at the store or online
Before buying, take these steps to confirm you’re selecting the correct Fram oil filter for your 2010 Forester:
- Check the packaging for the exact vehicle fit notes and part number, then compare with Fram’s cross-reference listings.
- If shopping online, use the retailer’s cross-reference feature or Fram’s site to verify compatibility with your engine code and year.
- Bring or note your current filter’s dimensions (thread size, gasket diameter, and height) and compare them to Fram’s specifications for the candidate parts.
Pro tip: If you’re unsure, ask a professional or call Fram customer support with your engine code (EJ25, EJ255, or equivalent) and your Forester’s trim level to get a definitive part number.
Summary
For a 2010 Subaru Forester, there isn’t a universal Fram oil filter number. The correct Fram part depends on the engine variant and the Fram line you choose. Always cross-reference Subaru’s OEM filter (commonly the 15208-series) with Fram’s catalog, and verify the exact part number using Fram’s cross-reference tools or a trusted retailer. When in doubt, confirm with a professional to ensure you select the precise filter for your specific Forester configuration.
