Perrin Performance Recirculating Blow Off Valve BOV BLACK PSP-INT-600BK

Blow Off Valves

Inefficient factory blow off valves (BOV) can hinder boost response during shifts and can limit the amount of boost pressure that can be built by your turbocharger. PERRIN offers this BOV for the 02-07 WRX & STi that can handle any amount of boost your turbo can create!

For clients that demand idle quality, and the best in drivability we offer a fully recirculated BOV. Like the stock BOV, the PERRIN recirc BOV keeps the vented air in the intake system to keep the ECU happy and running smooth. BOV's that vent to atmosphere can run rich between shifts causing backfires, can cause idle issues, and part throttle drivability on cars that have MAF sensors. This is due to metered air, the ECU thinks is being ingested by the engine, being expelled to the atmosphere. Popular cars with MAF sensors, are all Subaru WRX, STi, Legacy GT, Forester XT, Mitsubishi Evolution 8-10, Nissan GT-R, and many other popular turbo cars.

With the PERRIN BOV, there is no reason to add more washers or change the spring to allow it to hold more boost. Perrin's BOV works very different than others in that there is no need to have a spring to hold boost! The boost pressure is put on the back of the piston to keep it closed, and helps keep the piston from lifting prematurely.

The PERRIN Recirc BOV has many adjustments to taylor it to your driving style and horsepower. You are able to adjust when the BOV releases, and how much it releases by adjusting the spring and flow control screw. These very unique features are things not found on any other BOV.

While some may be wanting a "loud" BOV, the PERRIN recirc valve can still be heard through your intake system especially if an after-market Short Ram or Cold Air Intake is installed. While this may not be loud enough to wake up the neighbors, it is loud enough for you to hear in the car.

This is for the BLACK finish. Please search our store for the RED version.
