Forge Motorsport recirculating blow off valve for 2002-2007 WRX and 2004-2021 STi. 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.
