My car is a 2015 Mustang GT and I could not find an air filter for it...so that is why I went online. Am really pleased with it.
I install the AEM filter (28-50029) on my 2015 Ford Mustang Ecoboost yesterday. It may be my imagination, but I have noticed definite changes in the performance and all of them are positive. I am a Mechanical Engineer and very observant of equipment condition and operation. Things I noticed: quicker throttle response, not significant, but noticeable. Increased pull off the line and a higher RPM before Torque and Horsepower drop. Before you could feel a drop-off prior to gear shifts. Now it seems to pull all the way to the shift point.
I'm going to keep my foot out of it for a tank of fuel and see if there are improvements in the fuel mileage. This may be the only true parameter that I can measure.
As I said, it may be my imagination or maybe wishful dreaming, but I believe that the performance has increased.
