K&N Cold Air Intake Kit: High Performance, Increase Horsepower: Compatible with 2011-2014 Ford F150, 5.0L V8, 77-2581KP

I like the throttle response and the growl under the hood after replacing the factory intake.

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 minsMPG ~ 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....

Was delivered super fast. Great product and was as advertised. Super easy, quick installation on my 2014 f150 5.0.There were two things I’m not completely satisfied with though. The metal portion that attaches to the top of the air box does not fit as tight as other brands I have owned in the past. There is a gap between the metal part and the air box so it fits fairly loose. The back retaining clip won’t stay clipped and keeps popping off because of this.The intake tube is also bent so that it is very high in the engine compartment. It touches the hood when I close it and rubs against the insulation under the hood.All in all though it works and is what I wanted for the price range.

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.

The Intake was very easy to install and it sounds awesome! It adds a deep throaty sound to the engine and also added about a 1.5 mpg saving. Definitely worth the money if your trying to add a couple HP and add a deep sound to your engine.Although the install was very easy, the fitting for the vacuum hose would not screw into the intake. I had to drive my truck up to Home Depot to buy a brass fitting to see if that would fit. It was not a success. I then went and bought a nylon pipe fitting and I had to take the entire intake out of my truck in the Home Depot parking lot just to screw the fitting in and eventually stripped it, but it works!
