Features:
The Boomba Racing high performance recirculating BPV has been designed to be a replacement for the OEM bypass valve and is precision machined out of aircraft grade billet aluminum. It features an internal brass piston design and is pressure tested to withstand over 70psi, allowing it to compliment even the most aggressive turbo builds. Higher spring pre-load allows for more boost under load and drastically decreases the amount of boost bleed from high performance modifications.
