These genuine OEM Subaru gaskets for the Subaru WRX and STi, are used between the intercooler and bypass/blowoff valve. Because this is a pressurized connection, a worn or cracked bypass valve gasket can result in a serious boost leak and may even lead to more serious conditions that can damage your engine. It is important to inspect and replace these gaskets from time to time, especially if you have purchased your WRX or STi used. Warranty Disclaimer: Subaru of America will only warranty parts installed on a car that has a matching VIN to that part.
Warranty Disclaimer: Subaru of America will only warranty parts installed by a CERTIFIED Subaru Dealership. The part being installed must also match the vehicle VIN. IE If you install an STi block in a WRX at your friends shop, do not expect a warranty claim to come through if it explodes! Please use your best judgement.
