Do any of you guys run an aftermarket cold air intake, and if so, what kind of gains in MPGs did you see? Also is the stock air box as restrictive as the airbox was on my '02 6.0? I changed it to an aftermarket box and saw some gain over stock. BTW, I have an '07 LBZ. Thanks, Mark.

YOur stock airbox is a really good design, there is no gains for aftermarket intakes other than sound (turbo whistle). IF anything maybe just a drop in replacement filter!!!
