Diverter Valve Mounting Kit for FWD Golf/Jetta/GTI Audi A3 2.0T FSI Turbo Transverse Engine. Piping assembly, silicone connetors, and clamp kit for mounting a mechanical type of diverter (or blow off) valve onto the 2.0T FSI engine bay. TIG welded stainless piping, mandrel bent, and elctro-polished. Can be used to mount any conventional diverter valve on the market that utilizes 1" (25mm) inlet/outlet connections. Unconventional Blow Off Valves such as the HKS SSQ or Greddy Type RS can be used if you purchase our  BOV adapters to convert the ends to 1" inlet/outlet. This solution allows you to use a more proven leak-free "mechanical" diverter valve of your choice on the engine without having to worry about the stock electronic unit leaking boost, especially if you use P/N: ATP-VVW-172 (block off device) on the stock electronic diverter. We also recommend the use of our high flow inlet pipe kit P/N: ATP-VVW-171 which has provision for the recirculation of the diverter valve installed using this mounting kit.
