I wish you luck on your search.
Is your air box sealed or open?
The Volant CAI on my 05 F150 5.4L was completely sealed and the air boxes intake ports were sealed against openings in the fender well and radiator bulk head. I was very happy with this system as there was no change in sound levels or tone. Like your AFE it was the biggest noticable change in performance on the truck. Volant is not interested in the 2011+ 6.2L SD's so I'm looking around.
