Subaru OEM BOV Gasket Subaru 2002-2005 WRX / 2004-2019 STI


SKU 21896AA072

These genuine OEM Subaru gaskets for the 02-07 WRX & STI, are used between the intercooler and bypass or blow off 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. It is also highly recommended that you replace these gaskets when installing a new or aftermarket bypass or blow off valve.


  • Note:
  • Gaskets vary depending on model and year, please choose carefully when ordering.
