Subaru Genuine Engine Oil Filter & Crush Washer Kit — 2 Pack (15208AA21A) OEM Fit, Factory Filtration

Keep your Subaru's lubrication system performing as the factory intended with this official Subaru oil filter and crush gasket kit. Subaru has issued updated filter designs, so the unit you pull from the vehicle can differ visually from the replacement in this kit. This listing contains one OEM oil filter (part 15208AA21A) and one matching crush washer (803916010) per kit; multiple pack sizes are available (1, 2, 3, 6, 12). Use the kit on supported model years and engine types listed by Subaru to maintain warranty alignment and filtration efficiency.

Which Subaru models and engines will this filter fit?

This genuine filter and gasket pair fits a wide range of Subaru models across several years. It covers most non-turbo and many turbo variants depending on model year; always cross-check VIN and engine code before purchase to confirm fitment.

• Outback and Legacy: 2013–2025 (4-cylinder models)
• Impreza: 2012–2025 (non-turbo versions)
• Forester: 2011–2025 (2011–2013 non-turbo; 2014–2025 all engines)
• XV / Crosstrek: 2013–2025 (all engines)
• Ascent: 2019–2025

How does this OEM filter differ from aftermarket alternatives?

OEM Subaru filters are engineered to the manufacturer's specifications and are tested to work with Subaru oil flow rates, bypass valves, and housing designs. Aftermarket filters vary in media quality and sealing tolerances, which can affect protection, fit, and oil pressure behavior.

• Factory-specified filtration media and construction
• Exact gasket and dimension tolerances for reliable sealing
• Designed to match Subaru bypass and flow characteristics
• Part numbers superseded to 15208AA21A for consistency

When should I change the oil filter and crush washer?

Subaru recommends routine oil and filter replacement intervals based on driving conditions and model year. Typical guidance is to change oil and filter every six months or about every 7,500 miles under normal conditions, but owners should consult their vehicle's maintenance schedule for the best interval.

• Follow the interval in your owner’s manual for exact timing
• Change filter when performing an oil service or by the recommended mileage/time
• Replace crush washer each time drain plug is removed to ensure proper sealing
• Use OEM parts to preserve fit and performance

What comes in the package and what should I expect visually?

Each kit contains one Subaru genuine oil filter and one crush gasket. Note that Subaru has updated filter styling over time; the replacement unit may look different than the original factory filter on your vehicle but retains the same fit and function.

• Included: 1 × Subaru oil filter (15208AA21A) and 1 × crush washer (803916010)
• Available in pack quantities from single to 12 for convenience
• Superseded part numbers consolidated to 15208AA21A
• Packaged for retail sale and ready for installation during oil change

Who is this for: This kit is aimed at Subaru owners and independent mechanics who prefer genuine replacement components to maintain factory-level filtration, sealing reliability, and correct fitment. It’s especially useful for those performing routine oil services on Outback, Legacy, Impreza, Forester, Crosstrek/XV, and Ascent models covered by the fitment list, and for fleets or DIYers who want spare filters and drain gaskets on hand.
