You'll get a lot of different responses on CAI - everyone has their favorite brand. Personally, my first CAI was Airaid and I've just stuck with it.
Tuner is a bit of a kerfuffle right now. With Bama getting slammed pretty hard lately, many people won't recommend them. However, I've had nothing but good experience with them in either of my last two Mustangs. GrabberBlue is doing a comprehensive head-to-head comparison of Bama and MPT
. AED and Lund also are favored. I think for the most part you will be fine with any of them.
