K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 57-2524-2

The instructions and diagrams were the best I have used when assembling anything. It was very easy to install with one possible exception. The two bolts provided for the mounting bracket could have been 1/4 inch or so longer. This would have made the installation a bit easier. Have not driven the truck (V-10 Ford F-350 dually) but my neighbor who borrowed the truck reported 11.75 mpg up from about 9 mpg.

F250 6.8L V-10. I found the intake kit very easy to install with good directions. I am very pleased with the performance difference in the kit. I installed it a few days before pulling my 5th wheel on a trip and accompanied it with a tuner for my truck which I had installed the week before. The combination of the two is incredible and go hand-in-hand. Very pleased. My truck is like a whole different truck. I'd recommend this to anyone that needs to maximize performance of their vehicle like I needed to.

My K&N experience After reading the other testimonials there isn't a whole lot more you can say. I am thoroughly impressed with your systems and filters. I installed one of your kits on my 2003, F250 Super Duty with the 6.8L V10. I wanted better efficiency and gas mileage and your product supplied just that. I have been impressed enough that I went and got one of your filters for my wife's Pathfinder and it too is showing better mileage along with running stronger. Thanks for the chance to let others know how well your products work. I just wish I had starting using them sooner.

Sounds great,definitely can feel the difference in the pedal on my 04 f350 dually 6.8l 4x4
