Twin turbo's are the best CAI.

But before that I had a Racer's Edge Carbon Fiber inlet. Seemed to work well, but fitment kind of sucked too.

I'm happy with my JLT CAI....

just a little tidbit. I talked to my cousin today, who works at the service department at a local Chevy dealer. I asked him about CAI and the warranty, since I am thinking of getting one. He said that they get a ton of Duramax Chevy trucks in there with CAI, tunes, and other stuff. They don't care at all about the mods when the warranty work needs to be done, UNLESS the person is a jerk or bad customer. SO, be nice and you should be okay, at least according to my information.
