The 2022 Subaru Forester with the 2.5-liter engine uses Subaru’s genuine oil filter, part number 15208AA15A.
In the 2022 Forester, which relies on the 2.5L FB25 engine, the filter is a canister-style unit with an anti-drainback valve that sits in a serviceable housing. The 15208AA15A designation is the most commonly cited match for US-market Foresters in this generation, though part numbers can vary slightly by market or production run. If you’re shopping outside the United States or at a dealer, always verify the exact catalog number for your vehicle’s VIN.
Overview of the engine and filter design
The 2022 Forester uses Subaru’s 2.5-liter flat-four engine (the FB25 family). The oil filter is a replaceable canister element inside a housing that threads or caps onto the unit, designed to seal properly with the filter gasket and maintain oil filtration during operation and startup. The standard maintenance guidance from Subaru emphasizes using a filter that meets the manufacturer’s specifications to ensure proper filtration, oil flow, and anti-drainback performance.
How to confirm the correct part for your vehicle
If you want to double-check the correct filter before purchase, use any of these reliable methods:
- Refer to the owner’s manual or the official Subaru Parts Catalog for your exact model year and trim.
- Check the current filter’s part number directly on the canister or its packaging.
- Contact a Subaru dealer’s parts department with your VIN to confirm the precise part number for your vehicle.
- Cross-reference reputable auto parts retailers’ listings by entering your vehicle’s year, make, and FB25 engine to verify compatibility (look for 15208AA15A or nearby variations that match the 2.5L engine).
Because small production updates can shift part numbers by region or over time, verifying with an official source or your VIN is the best way to avoid surprises at the parts counter.
Notes on aftermarket options
Aftermarket oil filters that meet Subaru’s specifications for the 2.5L FB25 engine can be used as alternatives to the OEM 15208AA15A. When choosing an aftermarket filter, ensure it has the same filtration capacity, gasket size, and thread engagement as the OEM unit. Brands commonly used by Subaru owners include established filter manufacturers, but always confirm compatibility for the 2022 Forester’s engine and housing design.
Summary
For a 2022 Subaru Forester, the typical and recommended oil filter is Subaru’s genuine part 15208AA15A, suited to the 2.5L FB25 engine. Confirm the exact number for your vehicle if you’re shopping abroad or if production changes apply to your region. Use the OEM filter for best compatibility and performance, or verify aftermarket equivalents that match the same filtration specs. Regular oil changes with the correct filter help maintain engine cleanliness and longevity.
