Turbosmart 25mm Kompact Plumb Back Blow Off Valve

The Plumb Back system recirculates all excess pressure back into the intake system. Great for enthusiasts not wanting to be noticed but wanting the performance and reliability benefits of a quality BOV.

Please note; that for twin-turbo applications, such as the Audi S4 2.7L (B5) 97-01, this will require two valves.
