AVO avoS2A01900AREDJ Blow Off Valve Red 02-07 Subaru WRX / 04-10 Subaru STI
We utilise the latest technology in lightweight internal valving to ensure optimum blow-off response at all times. The design of our V2 BOV has been updated with new internals to better manage compressor surge. AVO blow-off valves are a 50% recirculate, 50% vent system that retains the return tube, keeping the stock computer system happy, while an additional vent with removeable plate sends hot air to atmosphere if you choose.
