This billet BPV/BOV Sound Plate allows you to vent your factory bypass valve / blow-off valve to atmosphere, which gives customers that iconic blow-off valve "whoosh" or "psssh" sound. This plate was designed with machined sound "trumpets" to increase audible noise. All hardware and O-rings included for a simple installation.


Technical Notes:

  • CNC machined 6061-T6 billet aluminum, anodized w/ O-Rings
  • Hardware

***Please Note: PRL does not recommend running a Blow-Off Valve on any metered air system, such as the L15 and K20 Turbo series engines***

If you'd like to chase sound, we always suggest chasing performance to back that up. There is really only one thing that happens when installing a Vent-to-Atmosphere (VTA) BOV on a car with a Mass-Air-Flow sensor (MAF). Rich Air:Fuel ratio when the BOV opens up.

This isn't a huge issue inherently, but it does affect some components adversely over time. Mainly your exhaust system. The rich conditions between shifts will cause unburnt fuel to exit the combustion chamber. This results in much higher Exhaust Gas Temps (EGT) and cause drastically more wear on catalytic converters. One other thing is potentially more fuel dilution in your oil because of the rich fuel condition, leading to shorter oil life, and other oil dilution issues.

Will installing a BOV on your car ruin your car? Definitely not.
Will certain components fail much sooner than if everything remained stock? Most Definitely.
