Subaru Engine Oil Filter & Crush Washer Kit — 2-Pack Genuine 15208AA21A with 803916010 OEM Fit for Outback Forester Impreza Crosst

Genuine Subaru engine oil filter and crush washer kit designed to protect your Subaru's engine by removing microscopic contaminants while ensuring a proper oil drain seal.

If you own an Outback, Legacy, Impreza, Forester, Crosstrek/XV or Ascent, this OEM kit replaces older Subaru part numbers and fits many 2011–2025 models. Subaru updated the filter design, so the physical appearance might differ from the one you remove during service; function and fit remain factory-specified. The kit contains one genuine Subaru oil filter (15208AA21A) and one crush gasket (803916010) per pack. Multiple pack sizes are available — choose 1, 2, 3, 6, or 12 filters to match your maintenance schedule or fleet needs.

How does this genuine Subaru filter differ from aftermarket alternatives?

OEM Subaru filters are engineered to Subaru's specifications for media efficiency, bypass performance and pressure tolerance. Choosing the genuine part reduces the risk of lower filtration capacity, inconsistent bypass behavior, or inferior seals that some aftermarket options may exhibit.

• Factory-tested filtration media matched to Subaru engines
• Correct bypass valve calibration to protect oil flow under cold or heavy-load conditions
• Exact fit dimensions and thread engagement for leak-free installation

Which Subaru models and years will this kit fit?

This kit covers a broad range of Subaru models across model years where Subaru specifies the 15208AA21A filter and 803916010 crush washer. It supersedes several older part numbers, so confirm fitment with your vehicle year and engine type before purchase.

• Outback and Legacy: 2013–2025 (4-cylinder models only)

When should I replace the oil filter and crush washer?

Follow the maintenance interval recommended in your Subaru owner’s manual: typically oil and filter changes every six months or around 7,500 miles, depending on driving conditions and local climate. Always change the crush washer with each oil drain to ensure a proper seal and prevent leaks.

• Change oil and filter per your owner’s manual schedule
• Replace crush gasket at every oil drain to maintain a secure seal
• Keep extra filters on hand if you perform routine DIY maintenance

What’s included in the kit and why the part numbers changed?

Each kit contains one Subaru genuine oil filter labeled 15208AA21A and one crush gasket 803916010 per filter in the pack. Subaru consolidated several older part numbers into 15208AA21A to simplify inventory; the updated filter may look different but is fully compatible with the specified vehicles.
