08-10 Subaru STI Perrin Recirculating BOV

The blow off valve is essential to all turbocharged vehicles. The purpose of the Perrin 08-10 STI blow off valve is to relieve compressor surge without reducing compressor speed. This Perrin recirculating blow off valve for the 08-10 STI controls boost pressure that is built up by the turbo and vents it into the atmosphere when your Subaru is not under load (in between shifts). This prevents pressure from backing up into the compressor housing, causing the turbo impeller blade to rapidly stop or even worse, to spin backwards (compressor surge or backspin). Doing so can be potentially destructive to the turbine wheel, shaft, and turbo life in your STI.

The Perrin Recirculating Blow off Valve for the 08-10 STI is a direct bolt on for a simple install. Since this blow off valve recirculates air just like your stock blow off valve, you will not experience a rich condition between shifts, or hear a loud rush of air expelled. The Perrin Recirculating Blow off Valve is rated to hold 190 psi, so this blow off valve will never leak under high boost pressures.

Note:
This BOV is designed to recirculate only and can NOT be set up to vent to atmosphere.
