The installation instructions are horrible. Look it up on youtube and it simplifies it so much and then it is very easy. Cannot say I have seen an improvement in mpg but you can feel the difference when you step on the gas. It sounds great too without being obnoxious.

Instructions are great.Installation was easy. Has a cool growling sound. A definite purchase before you buy a performance exhaust. Plus I would recommend the k&n drycharger wrap with purchase.

When I installed this kit, which took longer than I planned due to the rigid crankcase vent tube, I was pleased with the fitment and appearance. During the test run I immediately heard the "throatiness" of the now more open intake. The throttle was more responsive and the truck was quicker off the line at traffic signals. Gas mileage took a hit....1-2 mpg. The truck really opened up after I installed a Magnaflow muffler. Improved sound and performance all around.

Very impressed with the 63 series aircharger on my F150. The additional acceleration is great and the sound is fantastic. One satisfied customer for sure. Great price as well.

So far, so good! Install went as anticipated. Instructions written by experts not thinking about details that a "first timer" might need. Not sure about "bang for the buck", sure is loud when you floor it! Mileage up just a little.

Pretty easy install. Kind of expensive, but definitely changes the sound of my truck. Haven't noticed too much for mpg change

New to the truck world, figured a CAI would be a great first step with my 5.0 (Low cost, easy install, great gains is what I've read). I'm far from a mechanic, I'm a programmer and I was able to install this in 20 min. Very easy and looks incredible. The COI makes my V8 sound like a V8 with a slight increase in responsiveness. For fuel economy I've noticed about 0.5mpg increase. Hoping a custom tune pulls out some more performance. Overall, I'm not completely blown away but am very happy!
