It was the first thing I did on my 2011 when I got it. Noticed that throttle response was a tad better and you could truthfully hear a difference from under the hood as well. I have an AFE fwiw
I don't think it can hurt, like said above any more air you can get is gonna help....now it's not gonna be something your prolly gonna feel on the butt Dyno, but i do think it helps...
