Keep your boost pressure high and steady. The Forge Motorsport Atmospheric Dump Valve (FMDV13A) is made for the Audi S4 B9 and Audi S5 B9. The standard factory valve has plastic parts inside that can break easily. This leads to lost power. Forge fixes this by using solid billet alloy and a metal piston. This new valve connects right to your factory wiring. You get a perfect drive, no warning lights, and a great blow-off sound.
