Our engineering team performed extensive dynamometer testing during the development phase to ensure that each AEM Brute Force cold air intake produces more torque and horsepower than the competition air intake systems.

To ensure that each cold air intake system produces not just peak torque and power, but useable torque and power at both light and full throttle, AEM performs three-axis testing to quantify gains made at different throttle positions. This ensures that it makes the most power at EVERY throttle angle across the rpm band.
