The aFe Quantum Pro GUARD7 dry air filter with a 5.5-inch by 4.25-inch flange and 9-inch height is designed for Quantum Series intakes. It combines injection-molded top and base construction with a three-angle velocity stack for even airflow. The GUARD7 media layers—five cotton gauze and two synthetic—prioritize protection, and captive screws secure the filter to the intake housing.
