Forge Closed Loop Dump Valve | Mitsubishi Lancer Evo 4/5/6/X (FMDVEVO15)

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 which are prone to failure, this uses a single piston single spring. This prevents our diverter valves suffering any of the failures associated with diaphragm type diverter valves.
