Made from billet aluminium, this recirculating diverter valve dumps the charge-air back into the air intake system keeping external noise to a minimum. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Unlike the Diaphragms valves this uses a single piston single spring 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. Gives you the sound you want, but keeps the performance! when increasing boost this is needed. The best choice if your looking to make your turbo spool quickly, have your car idle like it just left the factory, and you won't be tricking the mas air flow meter in between shifts, which leads to smoother gear transition
Fits evo 4/5/6/7/8/9
