    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

    Boomba RBV

    Good quality, can handle high boost & better look than stock, but don't expect a better turbo sound, it actually did my turbo more silence. If you're looking for better turbo noises, an intake will do a better job or just get a BOV and deal with the CEL

    Solid product

    This is a simple bolt on. It offers a better look better “swoosh” sound and better build quality. If you are looking for a cheap upgrade this is a favorite of mine. The new recirculating design fixed the CEL issue on earlier models.

    BPV vs BOV

    The factory stamped steel BPV with a rubber diaphragm bothered me when I got my car. I purchased the BOV initially when boomba released it and loved the ability to comfortably run higher than stock boost levels plus it made all the fun turbo wooshy noises. It did leave a slight lag in boost between gears though. When boomba released the BPV the fun turbo noises got muffled down however the lag between gears was nearly gone. The install time is less than 20 minutes with the right tools and easily accessible.
