I just installed a JLT cold air intake. It was a very straight forward install. Tuned with my SCT Touch Screen Xtreme. There is a notable increase in sound at WOT. Hey, it runs good, sounds good, so I'd say it's a solid setup. Can't really notice an increase in power, but I guess that's to be expected for a CAI. Just wanted to give my experience and opinion. Monday the JBA longtubes, midpipe, and catback go on. I think this is the first time I said that I can't wait for Monday.
