This high performance recirculating bypass valve is precision machined out of aircraft grade billet aluminum which is far superior to the cheap plastic factory piece. 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 BPV opens and releases the pressurized intake charge. Designed to be a replacement for the OEM bypass valve and is available in 4 different colors.
No aftermarket tuning required. Will work on stock tune or aftermarket tunes. This piece does not throw any check engine lights, does not cause any turbo lag, and does not make the vehicle stutter between shifts.
