Boomba Recirculating Bypass Valve | 2017-2021 Honda Civic Si (040-00-004)
Boomba Racing Inc.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.

Customer Reviews
Nice quality installation is a little difficult because of limited space but worth it. Turbo sounds are much louder and it seems like I can reach boost all the way to 24psi easier. I reused the stock tubing on rbv because the one they supplied was too short.
This part is far superior to the factory valve. My boost psi hits higher at around 24 psi and stays steady.
This thing is awesome. I have a k&n intake and it flutters when I shift now. 10/10 recommend.
This product is the best one for the best price.
Performance wise it does the job. been able to hit 20psi at least on visual... Not really any sound though... Might need a Intake not sure.
