It's important to know how we stack up against stock and our competitors in order to be the best. We mount each intake system on our test equipment to measure the airflow from zero to the max CFM of the vehicle. We then compare the results and make design changes until we have maximized the airflow while still protecting your engine.


While airflow is important, it is equally critical to insure that your investment is protected. To do so, we first determine the max CFM the vehicle will generate at wide open throttle as it is more difficult to stop dust the greater the airflow. We then start pulling this amount of air through the intake while literally shooting fine particles of dust at the filter. Any dust bypassing the filter will be caught in the absolute blanket to determine the efficiency.
