Perrin Blow Off Valve Recirc Black Subaru WRX 02-07 STI 04+
Inefficient factory blow off valves (BOV) can hinder boost response during shifts and can damage your expensive turbo charger. PERRIN offers several choices for owners to choose the best solution to the problem. Fully recirculated (Recirc shown)
For clients that demand proper air fuel ratios and idle quality we offer a fully recirculated BOV. The internal design allows the user to change the volume of recirculated air, spring tension and sound. It also incorporates an industry leading boost chamber that does not place pressure on the piston surface that would otherwise force it to open prematurely. It will only release pressure when shifting. This condition is common with our so called competitors, leading to serious tuning issues and reduced power. Capable of handling more than 190 psi, there simply isn a boosted engine that our BOV can handle. Vent to atmosphere (VTA see PSP-INT-620) Many clients simply want the street presence of a loud phhsst when making a high rpm shift. If that sounds like you, we have your needs covered. With exclusive harmonic amplification cutouts, this valve is LOUD! Also, adjustable spring tension helps reduce rough idle and stalling found in other products.
Fits: WRX 02-07 and STI 04-08
