Easy to install. Took about 45 minutes. Truck sounds really good at idle and even better when I get on it with stock exhaust. Have seen fuel mileage yet because I’m heavy on the gas with the new sound. Kids like it too.

Ok, here's the scoop pull up a chair......... Install ~ Easy just take your time don't over tighten or strip screws easy peasy 25 mins MPG ~ I am sure it may have a positive effect as my MPG went from 17.8 to 18.2, HOWEVER... with the amazing throaty sound you get stomping on the pedal gas mileage will fall fast! Go easy it will save. Sound ~ WOW!!!!!! My 2013 F150 with the Coyote 5.0 really sounds awesome, get on the highway at 40-50mph and stomp it down and everyone in a 30 foot radius will look over and go WTF was that? LOVE IT!!!! HP ~ Haven't noticed anything but a little faster acceleration, nothing you will notice without a dyno tune! Price ~ Pricey, at almost $300 bucks I got the chrome pipe for looks, and for a pipe some gaskets and an air filter not sure I can say its worth the $$$.. Its your call, if you want your vehicle to sound and feel BAD ASS? Get it! if you want to save 1 mpg put $300 in your savings account instead :) In closing, I will say I Love it, and I feel it was worth it, heres a couple pics.... ... show more

    • What I was hoping for
Style: 50 State Legal
I wanted some more sweet sound from the 5.0 but I didn't wanna do any non-reversible or expensive mods. I peeped this kit out and one of the reviewers said that it sounded good and loud enough that they no longer wanted an exhaust. I had to see for myself, so after installing it and driving around I can say the same thing. It sounds great in all the right ways. It's got a great tone when you get on it and shuts right up when you let off. At slight throttle it's like stock. Give it a little more though and you get nice sounds without having to tach it up too high. I love the characteristics. That being said, YMMV but really it's made for a specific range of trucks with one engine, so perhaps not really. Either way, I'm extremely happy and I'm pretty sure you'd be too if you're looking for the same thing. It's a lot less than exhaust work and I'm glad I went this route first. ... show more

    • Great purchase!! As advertised!!
Style: Metal
Great product!! Nice fit and finish. Air box upper and lower could be a better fit. It would be nice if K&N would figure out a better gasket material to seal that particular area. Easy install, just follow directions. It took me under 30 minutes outdoors in Northern Maine winter with hand tools. Remember to disconnect your neg. battery terminal, as your Ford truck will learn where it needs to be after the computer is cleared. As advertised, better throttle response, and less hesitation. The truck seems to pull harder at higher RPM, so definite horsepower gain!! The engine roars when you tramp on it!!! I love that sound! As far as mileage goes.... don't yet know, I haven't really driven that much since the installation. ... show more

    • Sounds great
Style: 50 State Legal
100% noticed increase in gas mileage. The sound it produces is great. Not obnoxious all the time. At constant travel speed its as quiet as stock but get on the gas and it has that great 5.0 deep growl. Couldn't be happier.

    • 2014 F150 XLT V8 fit great, MPG gained, louder than expected
Style: 50 State Legal
Super easy to install and even with me getting on it to hear the v8 roar now I've gained 2.3 mpg even with bigger tires and leveling kit. I did have to contact K&N due to one of the pieces being the wrong one. I had to wait till the weekday to call due to no customer support on the weekends but the guy was super helpful and expedited it so the new piece took maybe 2 days to get her. Defintly reccomend but its louder than you think it would be. ... show more

Style: 50 State Legal
Easy to install only thing is when installing the maf sensor adaptor make sure you install it facing the right way and not backwards I put it on backwards first time and my truck would start then shut right off. If there were better instructions on that part I would say nothing wrong about this intake but I have noticed my mpg increase no noticeable power but make sound better too ... show more

    • So very happy with this product
Style: 50 State Legal
I cannot believe how awesome my engine sounds now. I have a 2014 f150 XLT with a 5.0 V8. Everything fit perfectly. K&N says install time is 90 minutes or less... if you have even the slightest knowledge of cars and can follow simple directions with pictures, it shouldn't take anywhere near that long. It took me maybe 20 minutes tops. All the parts are high quality and came for a great price. I was very pleasantly surprised at how awesome my truck sounds now. SO aggressive! I can definitely feel a quicker throttle response and more horse power. Haven't noticed any better fuel economy but that is definitely due to the fact that I slam the gas peddle any chance I get now. That sound change for such a simple upgrade is very addictive. I will definitely buy again for my next truck. ... show more
