Did one trip so far didn't notice any difference in fuel milage. Performance wise not much of a difference so far.

my truck has the 6.0 vortex max so was pretty peppy already. I went two sizes up on tire size which took away some acceleration but after installing the intake I noticed better throttle response off the line and on highway. Went ahead and got the scoop to complete it, don't know how much it helps but can't hurt. Overall pleased.
