Review on AEM 21 8014DC Metal Intake System by Bankroll Reed

Installs in about an hour. Under the hood it looked very sexy. My goal was to squeeze an extra 0.5mpg on 8.1 throttle. 300 km driven to test. CAI let out a high-pitched whistle (angry). No noticeable difference in performance when towing our trailer over the pass. The MPG was the lowest I've ever gotten for 2 consecutive fill ups! Sent it back to Revain and put the original recording back in. I'm done with CAI. My experience has always been disappointing😐
