  • Simple install (about 30 minutes). Sounds great and adds some quick pickup in acceleration. Very pleased.
Style: BlackHawk
I installed this last evening. I have never really done any work on a car, and install was easy as heck, took about 30 minutes. I installed it on my brand new 2015 Ford F150 5.0L V8. In case anyone is wondering, I spoke with Ford and they said installing this should not void any warranty. This thing sounds great when you give it some gas, and definitely noticed an improvement in pickup and acceleration. It is a tad expensive for what you get, but overall I'm very pleased with this Air Intake and I have a buddy who once to install in his F150 after seeing it. Quality seems pretty good as well. ... show more

  • Easy Install!
Style: Metal Intake
Quality cold air intake system! Everything was well thought out and all parts supplied. After installing on the 5L V8 Ford Coyote it's noticeably more snappy and definitely has a deeper, throaty sound...very noticeable over factory intake.

  • Sounds pretty mean
Style: Roto Molded
I will say the intake makes my truck sound pretty mean now. It took about 30 mins if that to install which I’ve installed a few before. Only problem I have with mine is it has alittle whistle to it but that’s it. I gained maybe 2 mpg but I got a lifted truck so I wasn’t expecting much lol. And great customer service cause I messed up my weather stripping and K&N sent me a new one for free! ... show more

  • Loooveee it !!!

No sound while normal driving, but when you are revving that engine .... OMG .... It sounds incredible 10/5. Also, very easy installation, did it with my buddies in about 30-45 minutes

  • Works great - wrong instructions included
Style: Roto Molded
The install was easy - after watching a video online. My instructions were for a Ford Escape - I have a Ford F-150 5.0L. It surprised me but gave me a good laugh. I can feel and hear the increase of horsepower - not sure about the milage as I haven't been watching that closely.
