Blitz Blow off Valve Kit for 02-07 WRX & 04-09 STi
The BLITZ Blow-off Valve for the 02-07 WRX & 04-09 STi relieves compressor surge without reducing compressor speed. It controls boost pressure that is built up by the turbo and vents it into the atmosphere when the car 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 and shaft.
The Blitz Dual Drive BOV is an excellent upgrade for your 02-07 WRX or 04-08 STi. Repeated stress over time can cause eminent damage to the turbo charger and eventually lead to turbo failure. A blowoff valve is actuated by pressure changes only, ensuring quick valve responses and complete closures at idle. The BLITZ blow-off valve not only improves performance and response, but also increases the life of the turbocharger.
Shipping costs are calculated upon checkout.
NOTE: The Blitz BOV vents to the atmosphere

Blitz Dual Drive Convert the Blitz Dual-Drive blow off from a 100% vent to atmosphere valve to a recirculating valve with the Blitz recirculating adapter. This adapter fits most cars with factory MAF sensors such as the Mitsubishi Evolution and Subaru WRX/STi to eliminate the rich air/fuel mixture that occurs when these cars run a 100% VTA blow-off valve.
