Aluminum Bypass Valve for Turbo Saab, Audi, Porsche, VW- Diverter Valve


  • Our aluminum bypass valve is a direct replacement for the plastic valve typically found on factory turbo cars from Saab, Audi, Porsche, and
  • VW. This valve is designed to hold more boost without leakage and also looks much better than the factory valve. It also has a higher flow
  • rate to better protect the turbo from surge situations. The kit comes with additional springs and a shim to adjust the opening pressure,
  • clamps, and vacuum hose.
  • These are also great for custom turbo builds that require a recirculated bypass system, or you can use this as a blow-off valve!
  • Here are the vacuum pressures required to open the valve with each spring:
  • Low 5”
  • Medium 8”
  • High 11”
  • Shim = 1.5” additional
  • This is an upgrade to the Bosch 0 280 142 102 diverter tube
