Forge Motorsport Recirculation Valve for Audi B9 S4, SQ5, and S5
This solenoid operated valve 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 are designed, manufactured and engineered by Forge to remedy the failures experienced with the OEM solenoid valves when the diaphragm or plastic piston fails - effectively resulting in a boost leak.
Forge valves use full billet alloy construction with a piston based internal design that provides significantly improved reliability, lightning fast response and will withstand additional tuning upgrades.
For those looking for more noise, an atmospheric version is available as well.
