just purchased a 2006 f 250 s/c short box with a 5.4 and was just wondering what would be the best CAI for this truck. going to look at a programmer also have decided on either an edge or sct.

 

To my knowledge, only K&N makes a full CAI kit for the 2005-2007 Super Duty 5.4L truck. I installed mine back in February and really like it. I later installed the SCT tuner. Together, they made a significant improvement in performance.
