Boomba Racing BPV/BLOW OFF VALVE BLACK for 2015+ Subaru WRX

See the video below to see how badly the stock BPV leaks! We were able to pick up 15 hp and 9 tq from switching to our piece.

This high performance recirculating blow-off valve is precision machined out of aircraft grade billet aluminum. It features an internal brass piston design and is pressure tested to withstand up to 75psi, allowing it to compliment even the most aggressive turbo builds. Spring pre-load determines the pressure differential required across the piston before the BOV opens and releases the pressurized intake charge. Designed to be a replacement for the OEM bypass valve and is available in 4 different colors.

-Larger cross section compared to stock

-100% recirculating 

-Higher flow

-Pressure tested to 75 PSI

-Easy install

-No need for re-tune

Installation is simple and all mounting hardware is included.
