Certainly de-clutters the engine compartment. Well made intake tube. Casting seams, while visible are smooth to the touch (no casting flash). Nice textured finish. Easy install. If you lift the air box lid to ease installation, be sure the lid is properly seated and latched before tightening any clamps. The supplied hump hose is a lot stiffer than the OEM intake tube's accordion connection. End result: clean appearance, a bit more intake sound (noise?) at WOT, as expected.

Cleans up engine compartment and really compliments running a catch can system on the 5.0 trucks. Factory air box is better at picking up cooler air from outside than any of the cai designs I looked at. This removes the "weak link."

Got an increase of torque off the line as well as a small improvement in MPG. A little work needs to be done by the vender regarding the fit of the EGR hose. It needs to be a bit lower.

Impressive on my 2013 F-150 5.0 Coyote!

Who would have guess that replacing the stock intake tube with this Airaid MIT can make such a difference. The installation was a breeze. Can not tell any difference over stock while idling but once I got it on the road, the acceleration and sound was impressive. I believe it's more of a gain than just replacing the already straight thru stock exhaust system. It's quiet until you get on it then it sounds like what a truck should sound like. A little pricey but lot less than a performance muffler

First off, I bought this mainly to improve the appearance of my engine bay. Installation is straight forward. Did it less than 10 minutes. Quality is good. There is a bit of a sound increase of the incoming air, but you have to really listen. I also have long tubes though so really hard to hear anything anyways. Don't buy this for hp or mpg gain as there are non or loss, but buy only to improve under hood appearance.

Didn't take long to install ,fit is pretty good but hadn't noticed any difference in performance or mileage. Intake noise is louder when acceleratin but that's expected , so did I waste $150 not sure
