The Plumb Back Blow Off Valve (BOV) is a fully recirculating system that redirects all excess boost pressure back into the intake, ensuring smooth and quiet operation. Ideal for enthusiasts seeking improved performance and reliability without attracting unwanted attention. For twin-turbo applications, such as the Audi S4 2.7L (B5) from 1997 to 2001, two valves are required.
