This stage 2 air intake system combines a 3-1/2 diameter black powder-coated aluminum tube and a massive 7-1/2 Pro DRY S air filter with inverted top to generate 32% more airflow. In recent testing this system produced 13 horsepower and 16 lbs. x ft. of torque. The Pro DRY S air filter is 3-layer progressive, cotton gauze filter that requires no oils and cleans with simple soap and water. The air intake is enclosed in a durable 18-gauge heat shield that utilizes the lower half of the factory air box that requires no assembly.
