Pretty sure I was the second owner of this setup, and like I was told, DEFINITELY improved my top end performance, but I don't spend most of my time up there, so went back to my hFit SupaSucka intake for the low end throttle response. Its HPS number is 37-581 and it can be converted to a short ram intake, also. I put maybe 5k miles on it, but the filter will need to be replaced. It got holed somewhere along the line. Forget what I paid for it, so I'll start out asking $80+shipping for it. If that is out of line, I get the feeling someone will fill me in. I'm in NW Ohio (Sylvania), and work in Newport, Mi so if you are anywhere close, we should be able to work out a meet-up to save you shipping cost, and me the hassle. I think I got pics in my phone, so I could text them to you if you send me you #. Thanks for checking my post.
