About this part

Cobb's XLF BPV bypass valve (712665) replaces the factory blow-off valve on the 2001–2007 WRX, including wagon and sedan. It cuts the valve's internal control volume by 30%, so it opens and reseats faster, and raises clamping force by 60% at peak boost to resist flutter under high manifold pressure.

Fitment

Confirmed for the chassis below. We list a chassis only where the part is on one of our cars or on the manufacturer’s own application list.
