I purchased this from Z1 a few years back and paid about $400 for it I think. I've decided to go a non-shiny route this time around so I'm putting this up for sale. Remember its a Z1 product so its far from perfect. If you check their site you will get more info on that. I would like to trade someone for their plenum plus $250. Bret (623)533-7334 Text or call.
