Boomba Recirculating Bypass Valve | 2017-2020 Honda Civic Si (040-00-004)

17+ Civic Si Full Recirculating Bypass Valve by Boomba Racing

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.
