After reviewing and searching old posts for info on TW and XR-Underground, I think I am going with the URD CAI. Mainly for the sound it makes. I want something loud (something to make people think the hood scoop is actually functional haha). The numbers ran on both seem to be about the same as HP and temp goes. There was an old thread that had the install pics on it. Anybody have or know the link to it. Thanks! And I dont mean to beat a dead horse here about CAI's.
BTW- XR underground is a pretty cool site too, lots of good info as well.
