The K&N kit not just the filter is the only way to go. Throttle body spacer, chip or programmer. I prefer the chip. Headers are a nice mod to these trucks but Hella expensive. A good exhaust redo until you can afford the headers would be a great help as well. Borla's sound awesome on a truck, for some reason they dound different on cars and trucks.. My experience is that on the 5.4 trucks the low tone isnt as easily achieved as on a truck with a 4.6.. Why I have no idea but Ive never heard one that has that LOW deep tone that alot of people want.
