Review on AEM 21 787C Cold Intake System by Robert Castro

Installation took about an hour and a half. We have installed other brand pipes on some of our vehicles before, compared to other pipes on this unit the sheet metal is thin and can bend at the ends if you accidentally drop or hit other parts. which can reduce efficiency. Upon arrival the heat shield has a 45 degree bent attachment point/bar making it unusable and difficult to install. Therefore, I cannot assume any liability for the processing of this device. When it comes to efficiency, what we see most often in our other cars is an increase in performance and improved fuel economy, which is why we ordered this. , this device has slightly increased power, the gas is more responsive, but has not improved gas consumption.
