I have a 13 GT premium. I bought my Airaid CAI used. As soon as I put it on I notice an excellent throttle response , with out a tune. I Also wanted to try the Airaid modular intake tube with a K&N filter and the stock box to compare. Needless to say, the CAI outperformed (car response) the modular tube and the stock box. so I decided to stick with the CAI and sold the modular tube. Now after I added the mufflers eliminators and a tune, the difference was like night and day. I will never go back to a stock box. Whether it might be just my butt dyno or not, I felt the difference. I say try it and see for yourself.
