I installed this AEM product on my 2014 Mustang GT. Installation was easy The instructions provided with the inlet tube were easy to understand and the diagrams/photos helped with the process all the more. Installation took me no more than 30 minutes and that was with me taking my time The longest part of the installation was removing the strut tower brace. That part is not mentioned in the directions but it is a no-brainer. You will not be able to remove the engine intake cover with the brace in place so off it goes.
Sorry to say that I did not have the Mustang long enough to give it a thorough going over such as gas mileage and the like as I fell pry to a 2015 Mustang GT two weeks later. But you can bet that I am going to add another AEM intake tube to this Mustang as well once I change out the exhaust. I should also mention that the AEM tube added style and class to the engine and it looked mean once installed. Too bad Ford could not have built something that looked as good.
I also got a little more of a howl when I went WOT and I mean that in a good way.
All in all, I am very happy with the unit, and the service I got from AEM. I will be happy to do business with them again
