These p ton-type valves can h le up to 4 bar (~60 psi) of boost have ~75% more flow capacity than stock valve. By reacting faster , turbo compressor stalling resulting turbo lag are greatly reduced. Each every valve pressure-tested prior to leaving manufacturing process. Highly recommended for all 1.8T engines , y are a very easy 20 minute bolt-in with included detailed instructions. Bailey Motorsports famous for ir strict quality control when manufacturing ir products , which means that you , user , ensured of proper performance. Available in pol hed silver matte black.

If you are running increased boost pressures, after a software remap (chip), or OEM valve being subjected to high temperatures, lifespan of unit significantly reduced. Even without any modifications taking place to vehicle at all, th OEM valve has been shown to fail over time itˇ¦s boost holding capacity also leaves some room for improvement. We now have worldˇ¦s first fully engineered solution offering both significantly improved reliability as well as valve related boost response. Our valve installation kit replaces original unit with a pressure/vacuum operated p ton valve that still also retains desirable OEM ECU control over valve actuation. Th product has been thoroughly designed tested with expressed intent of offering improved valve response maintaining ECU control while resulting in absolutely NO fault codes, NO check engine lights, no adverse effects of any kind. All of necessary components detailed instructions are included everything designed to make installation as simple as possible. Th product applicable for all of following 2.0 FSiT applications:VW Golf MK5 GTI/Jetta GLI, VW Eos, VW Passat (B6) Audi A3, Audi TT Audi A4 (B7) SEAT Leon Skoda Octavia | |
