I have a HKS SSQ blow-off valve that came off my 06 wrx. Not sure of the mileage on the part, as it was on when I bought the car. It was working fine before removed, I just went back to the stock bypass valve. It also comes with the plug to cap off the return hose going back to the turbo. I believe this will fit on 02-07 wrx/ sti. I'm looking to get $150 shipped.
