Specially built blow-off valve that will work on most any 1.8T application. Made to be mounted right on top of hard boost pipe.
Made from billet aluminum this atmospheric diverter valve dumps the charge-air to atmosphere creating the Whoosh sound when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.Unlike single piston or diaphragm diverter valves this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.
