Subaru Engine Oil Filter & Crush Gasket Kit — 3-Pack OEM 15208AA21A with 803916010 for 4‑Cylinder Outback/Impreza/Forester

Genuine Subaru Engine Oil Filter and crush gasket kit (15208AA21A & 803916010) for a clean, protected engine — sold in multi-packs so you always have the correct OEM parts on hand.

This kit contains an authentic Subaru oil filter and matching crush gasket engineered to trap microscopic contaminants and maintain proper oil flow. Subaru updated the part numbering, so older filters you remove may look different than the current 15208AA21A replacement; the listing replaces several superseded numbers to simplify fitment. The kit is available in multiple pack sizes and fits a wide range of Subaru 4-cylinder engines and model years listed below.

How does a genuine Subaru filter benefit my engine compared with aftermarket options?

OEM Subaru filters are manufactured to the automaker’s specifications, ensuring consistent filtration efficiency, correct bypass pressure, and a proper sealing interface with the crush gasket. That reduces the risk of premature wear from abrasive particles and helps maintain stable oil pressure between changes.

• Engineered filtration media traps microscopic contaminants
• OEM gasket size and crush characteristics ensure reliable sealing
• Designed to work with Subaru-specified oil flow and bypass settings
• Manufactured to Subaru quality standards to reduce variability

When should I replace the oil filter and crush gasket?

Replace the oil filter and crush gasket every oil change, or follow the interval in your owner’s manual. Subaru often recommends changing oil and filter around every 6 months or 7,500 miles depending on driving conditions, but consult your vehicle’s maintenance schedule for the precise interval for your model and driving habits.

• Change filter with every oil change for best protection
• Replace crush gasket each time to ensure a leak-free seal
• Use OEM parts to maintain warranty and service consistency
• Check owner’s manual for time- or mileage-based intervals
