Hey,I have a HKS SSQV blow off valve with around 5000 miles on it. Still looks new.Comes with the C Clip, cant find the Oring, but I had it yesterday. If I find it I will throw it in, if not buy one from ACE Hardware.Asking 140 shipped Paypal. I will ship same/next business day via USPS Priority.Also, this is a legit one purchased from Modern Performance. No PRC stuff here!Thanks!Tim Klein
