Keep your boost inside the intake where it belongs, and cure common driveability concerns with this stronger, more durable VW/Audi valve, suitable for stock or mildly tuned cars.

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.

Symptoms vary, but commonly include rough idle, a loss of power, or an illuminated check engine light.

Easy to install, you'll need one sooner or later, so be prepared.
