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.

Features

  • 100% recirculating
  • Higher flow
  • Tried and true brass piston design
  • Makes cool boost noises
  • Pressure tested to 75 PSI
  • Easy install
  • No need for re-tune

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.

Applications

  • 2017+ Honda Civic Si

What's In The Box?

  • 1 - Boomba Recirculating BPV

Warranty

  • Manufacturer Standard Warranty

2020 SI Boomba BPV

Very well made part! Fit and finish are very clean. Install is kind of a pain. Even moving the wiring doesn't help much. Do yourself a favor before you install. Need a 8mm deep socket 1/4 drive and a piece of vacuum line about 8 to 10 inches! Once the stock part is in your hand the comparison is night an day. The Boomba valve works as well as it looks. Definitely recomend!

Great Performance

I have a 2019 civic si sedan with a PRL Green Filter and no other mods until installed my BPV and man did it make a difference. The stock valve in my car tended to falter a bit under pressure and didn't quite let my car reach it's full boost potential, I'd get around 16-17psi at 65°f outside. Once I installed the new valve, I'm hitting 18-19 consistently at 80°f and every so often I get a 20psi reading at 65°f! So not only did the boost become more stable it actually was able to boost higher because of the stronger boomba valve design instead of the stock diaphragm valve. As an added bonus, this thing sounds great with the green filter and even gives flutters when you lift off the throttle at full boost.

Great product. Boost feels alot more consistant. My stock valve fluttered alot under hard accel. This valve solved that issue for me.
