Hot Damn, I just came back from a road trip, I hit 18 mpg without doing anything to my truck. I just installed the K&N CAI today...YES, I did it myself (I am moving up with projects). I musxt admit, the hardest part was installing the seal on the heat shield. Next week I will be adding my tonneau cover (I decided to go for a hinged soft tonneau cover instead of a hard tonneau cover, in order to save on costs) to further increase gas mileage. Anyways, as promised here is a pic of my new daily driver. I was going to get a black truck or a Harley Davidson Truck in order to match my Stang, but decided that black is too much trouble to keep looking good and having one black car is enough. Enjoy.
