This is an OEM Subaru compressor bypass valve, otherwise known as a blow-off valve. Is your car not making the boost that it should? A defective CBV might be the culprit.
Comes with new gasket.
Fits all 2005-2009 Subaru Legacy GT and Outback XT. (The 2008 WRX actually uses this Legacy GT-style valve, too.)
