This is a direct bolt-on replacement for the factory bypass valve and was designed to the be THE BEST blow off valve on the market. Using a large 44mm piston and Viton O-rings to withstand the high air charge pressures and outlet temperatures from your turbocharger.

The Design is a exercise of Function Aesthetic. The crown of the cap is notched perfectly for placement of fingers making it easy to tighten, loosen or remove. The custom machined 304 Stainless Steel banjo fitting with low profile 10mm banjo bolt is pure automotive jewelry.

The Hybrid Inlet Slot is aligned perfectly to the OEM Outlet slot for smooth airflow. The center Recirculating Outlet allows some of the air to flow back to the turbocharger inlet keeping the ECU happy and your car Check Engine Light free. The Vent to Atmosphere Ports are positioned around all three sides of the valve to give you and everyone around you that perfect “Psssh!” between shifts. The ports themselves feature a megaphone-style design for maximum sound levels.

Made in the USA, every detail on this valve screams quality and precision, right down to the position of the Hybrid Slot and shape of the Vent to Atmosphere Port making that perfect “Psssh” between shifts. Each 6061 aluminum valve is anodized for beauty and durability in your choice of Red, Blue, Gray or Black.

***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.
