Subaru’s genuine oil filter is designed to fit the 2015-2025 WRX and related models with the same filter body. The part is manufactured in Japan and is marketed as a high-quality, universal-fit filter. Using an OEM filter helps ensure proper filtration, consistent oil flow, and compatibility with the engine’s oil pressure requirements. This option is ideal for owners who want a straightforward, factory-backed replacement during scheduled maintenance or a quick refresh.
Subaru Set Of 3 Oil Filters And Crush Gaskets – 15208AA170 & 803916010
This set provides three oil filters and accompanying crush gaskets, all genuine OEM parts. Ideal for a multi-oil-change plan or rotating maintenance, it minimizes downtime by keeping a ready supply of filters on hand. The filter assembly is designed for compatibility with the same WRX/BRZ engine family and helps ensure a proper seal to prevent leaks and maintain oil pressure.
Subaru OEM Synthetic 5W-30 Motor Oil 5 Quart Bottle
OEM synthetic 5W-30 motor oil is formulated for Subaru engines, including turbocharged WRX units. The 5-quart container is suitable for a full oil change, and the oil is designed to work with modern emissions systems while offering strong high-temperature protection and good shear stability. This option aligns with factory specifications while supporting engine longevity in performance-oriented driving.
Subaru Genuine SOA427V1410 Oil Change Kit (5W-30) Turbo WRX STI
The kit combines filter, crush gasket, and a 5-quart supply of synthetic 5W-30 oil designed for turbo WRX and STI models from 2011-2013. It provides a complete, factory-backed maintenance kit that helps ensure proper filtration and lubrication, reducing the risk of leaks and maintaining optimal engine performance within OEM parameters.

The combination of a factory-filter and a full oil supply makes this a comprehensive option for a single-service replacement.
Buying Guide: Key Purchase Considerations
- OEM vs. aftermarket parts: OEM Subaru filters and gaskets are designed for exact fit and compatibility, while high-quality aftermarket options can save money but may vary in filtration efficiency or seal performance. For turbo WRX applications, OEM kits minimize risk of fitment issues.
- Oil specification: The WRX typically benefits from 5W-30 synthetic oil with good high-temperature stability and low-SAPS formulations to support emissions systems. Confirm the oil meets or exceeds OEM requirements for your model year.
- Filter compatibility: Ensure the filter part numbers match your WRX generation. Subarus often use the same family of filters, but there are revisions over model years that require precise parts (e.g., 15208AA170, 15208AA100).
- Gasket integrity: Crush gaskets are essential for a proper seal at the oil filter housing. A kit that includes both filter and gasket reduces the risk of leaks after service.
- Oil capacity and servicing intervals: WRX engines commonly use around 5 quarts of oil per change, plus any sump capacity considerations. Long-drain specifications can improve overall maintenance intervals, especially in performance applications.
- Emissions and engine health: Oils with low-SAPS content are designed to protect emissions control systems, including particulate filters and catalytic converters, which helps maintain system performance over time.
- Warranty considerations: Some owners prefer OEM kits to preserve the vehicle’s warranty or ensure compatibility with dealer maintenance protocols.
Overall, for WRX maintenance, combining a genuine Subaru oil filter set or kit with a high-quality synthetic 5W-30 aligns with OEM expectations and supports engine longevity under turbocharged operation. The Motul 8100 X-clean EFE offers a robust alternative for drivers seeking extended drain capability and emissions-system compatibility, while Subaru-specific kits provide a complete, factory-backed maintenance path.
