Subaru OEM Oil Separator Cover WRX / STI 2002-2021 | Genuine Replacement | 11831AA210
Video description
Restore your engine with a Genuine Subaru OEM Oil Separator Cover. If you're rebuilding your EJ engine or performing preventative maintenance, replacing the oil separator cover is a smart upgrade that helps maintain proper crankcase sealing and long-term engine reliability.
Over time, the factory oil separator cover can become brittle, crack, or leak due to age and repeated heat cycles. Installing a new OEM replacement while the engine is out helps prevent future oil leaks and saves time compared to replacing it later.
Fitment:
Subaru WRX (2002-2021*)
Subaru STI (2004-2021)
Fits a variety of Subaru EJ-powered models
