Check out the Vaico diverter valve for your B5 S4. Keep your boost inside the intake - where it belongs. Cure common driveability concerns with this stronger, more durable 710N valve.

Diverter valves live in a tough neighborhood. By definition, they limit turbo boost, and most eventually fail due to a pin hole or tear in the valve diaphragm. The 710N Valve is a diaphragm-based, factory upgrade for a lot of applications. The 710N valve was originally found on the TT225, and is known to have a tougher internal diaphragm that can withstand higher boost levels.
