Alloy Recirculating Ram Dump Valve available to fit the Impreza V5. 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

If you wish to tune this product to fit the needs of your engine, please see the spring tuning kit below.
