Adjustable Dual Port Blow Off Valve
Condition:
Brand new in box available in BLUE.
These Blow off valves are direct fit (no welding required) for the following
vehicle makes and models:
- 2008 - 2014 Subaru Impreza WRX (will not fit 2002 - 2007 WRX, please view our other listing for a different BOV)
- 2005 - 2009 Subaru Legacy GT
- 2002 - 2007 Subaru Impreza WRX
Mazdaspeed 3 2007-2013
Mazdaspeed 3 2010-2013 BL series, but will require an aftermarket airbox to have room for the BOV to fit too.
Mazdaspeed 6 2006-2007
Mazda CX7 2.3L 2006-2012
These units are fully adjustable and can operate under any of the following main conditions:
- Fully venting off to the atmosphere (AKA Supersonic)
- Fully Recirculating (AKA Plumb back)
This Blow off Valve is fully adjustable to every individual's preference as to how much air gets vented off to atmosphere and how much is being recirculated. This is easily achieved by twisting the top chamber clockwise (to make it tighter so it opens at higher boost levels), or counter clockwise (to make it softer so it opens at lower boost levels).
