Blitz Blow Off Valve

Product Description

The Blow-off valve (BOV) is important to all turbocharged vehicles in order to relieve compressor surge without reducing compressor speed. The BOV controls boost pressure that is built up by the turbo by venting it to the atmosphere in between shifts. This prevents pressure from backing up into the compressor housing, causing the turbo impeller blade to rapidly stop or to spin backwards, which can be destructive to the turbo. 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.
