Forge Motorsport Recirculating valve for the Audi S4 B9

This product is a solenoid operated valve that integrates seamlessly with the OEM electronics resulting in absolutely no fault codes, no check engine lights, and no detriment to the performance of the vehicle in any way. These valves, designed and manufactured by Forge are engineered to remedy the failure issues experienced with the OEM solenoid valves when the diaphragm or plastic piston fails which would effectively result in a boost leak.

Forge Motorsport panel filters are a lifetime washable product, we recommend cleaning your filter every 10,000 miles or every year (whichever comes first). On top of saving you money on replacing the OEM paper filter annually, the filter being washable and more importantly reusable is much better for the environment.
