For my 12 I got the Airaid intake tube. Pretty cheap, cleans up the intake assembly, doesn't really add much more noise but there is a slight difference. Put an Accufab TB, the intake tube, and axle backs on before I got a tune. Gave that info to Steeda and when I uploaded the tune today, night and day HUGE world of difference. It's all in the tune. Thanks Steeda
