Full recirculating BOV. The Plumb Back system recirculates all excess pressure back into the intake system. Great for enthusiasts who do not want to be noticed but want the performance and reliability benefits of a quality BOV.
Please note; that this will require two valves for twin-turbo applications, such as the Audi S4 2.7L (B5) 97-01.
