The correct oil filter part number for a 2016 Subaru Legacy depends on which engine is in the car. For the common 2.5-liter engine, Subaru’s OEM filter is typically 15208AA131. If your Legacy is equipped with the less common 3.6-liter engine, a different filter number applies. Always verify with your VIN or the existing filter to be sure.
Engine options in the 2016 Legacy
While the 2016 Legacy lineup in the United States mostly used the 2.5-liter four-cylinder engine, some markets offered the 3.6-liter option in certain trims. The oil filter part number corresponds to the engine family rather than the trim level, so identifying the engine is the most reliable way to confirm the correct filter.
- 2.5L FB25 engine: OEM oil filter part number 15208AA131.
- 3.6L EZ36 engine (found on some non-US markets or older trims): OEM oil filter part number 15208AA132.
Note: If your Legacy’s engine is not clearly identified or you’re unsure which engine your vehicle uses, confirm with a VIN lookup in Subaru’s official parts catalog or consult a Subaru dealer to avoid ordering the wrong filter.
How to verify the correct part number
To ensure you order the exact oil filter, use these verification methods:
- Check the filter you remove for the printed part number, or note the filter’s threading and gasket size if the number isn’t visible.
- Lookup your vehicle in Subaru’s official Parts Catalog using your VIN to retrieve the precise OEM filter for your engine and model year.
- Consult your owner’s manual or service manual’s maintenance section, which often lists the correct filter by engine type.
In practice, most owners replace the filter with the OEM part that matches their engine, and they pair it with the oil grade specified in the manual to maintain warranty coverage and optimal performance.
Alternatives and aftermarket considerations
While Subaru OEM filters provide a guaranteed fit, reputable aftermarket options can be suitable when carefully selected. If you choose an aftermarket filter, ensure it lists compatibility with Subaru FB25 or EZ36 engines, and verify correct thread size and gasket diameter. Always confirm fitment before purchasing to avoid compatibility issues.
Bottom line
For the 2016 Subaru Legacy, the most common oil filter part number is 15208AA131 for the 2.5L engine. If your Legacy uses the 3.6L EZ36 engine, the appropriate part number is 15208AA132. Always verify with VIN lookup or by inspecting the existing filter to ensure you order the correct part.
Summary
Identifying the correct oil filter part number for a 2016 Subaru Legacy hinges on knowing the engine. The 2.5L FB25 engine typically uses 15208AA131, while the 3.6L EZ36 engine uses 15208AA132. Use VIN-based catalogs, the owner’s manual, or the current filter itself to confirm the exact part before purchasing. This approach helps ensure proper fit and performance and avoids cross-compatibility pitfalls.
