We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner. Service Kits can be found here
Alloy Recirculating Valve available to fit the Impreza 2001 onwards models including the 2009 GR 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.
