Audi B6 A4 1.8T Performance Diverter Valve Options
Turbo compressor surge is a harmful effect of boost pressure that is not released when the throttle body plate is closed. Thankfully Audi implemented a diverter valve to relieve pressure and keep your turbocharger safe. Over time your diverter valve can show signs of weakness and either stop working completely or leak, which both can have negative effects on your vehicle. If your diverter valve is on its last breath consider replacement sooner than later. We have a wide range of options for just about everyone's needs. We also have some great accessories as well!
Upgrade your valve.
