To be straight to the point, the AEM intake has been a wake up call to my engine. Really enjoying this product. Having the ecoboost has been interesting to modify and Mustang lovers are quickly warming up to the car. The CAI from AEM overall gets a 5 from for reasons I'll share. I notice it most of course when the boost kicks in around 3,000 rpm.
