Forge Blowoff Valve FMDV14T for VW/Audi 2.0T FSI/TSI

If you don't want to spend the extra cash to replace your entire diverter valve, but still want the blow-off sound try the Forge Motorsport Blowoff Adapter. It sandwiches between your factory diverter valve and the mounting point. When your diverter valve actuates, this valve allows blowoff to atmoshere rather than recirculation, and has a nice aggressive sound. Comes with mounting hardware.
