I have a new model HKS SSQV blow off valve that was only used for about 2 weeks on my car. Its got a few marks on it from installation, but works just like new. It's got adapters on the inlet and outlet for 1" hose, so it is set up for recirculation, but both can be removed, and the original fins can go back in the outlet.

Bought this for $200 plus extra for the adapters and barely used it. I'll sell for $175 shipped. Make me an offer if you want, I need this gone.
