The Perrin Fully Recirculated Blow Off Valve is capable of handling more than 190 psi; there is no boosted engine that the Perrin recirculating BOV can't handle. This BOV is a direct bolt on for Evolution 8 & 9 owners and can also be used as a universal BOV. For car enthusiasts who need to maintain proper air fuel ratios and idle quality this fully recirculated BOV is perfect. The internal design on this Perrin valve allows you to change the volume of the recirculated air, spring tension, and sound.
The recirculating valve features a 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. Perrin's industry leading boost chamber design solves the common problems seen with other BOVs on the market. Wave good bye to tuning issues and all that reduced power.
Note: Universal BOV- direct bolt on for Evo 8 & 9, does not fit MR.
