IAG Replacement BOV Elbow 2002-2007 WRX/2004-2021 STI

The stock Subaru compressor bypass valve has a cast elbow part bolted to it that is not available separately. (The compressor bypass valve, also known as a “blow off valve,” or “BOV” releases compressed charge air when you back off the throttle.).This part from IAG replaces your missing or damaged BOV elbow. 

Another benefit is that you can install the IAG elbow 180-degrees upside-down, which can be useful for front-mounted intercooler setups, or other non-standard piping arrangements.

Fasteners and an o-ring are included. Choose from silver or black elbow color.

Blow-off valve not included.

Fits all 2002-2007 WRX, and 2004-2021 STI.
