aFe Magnum Force Super Stock Pro 5R Air Intake Systems 55-12550

aFe Magnum Force Super Stock Pro 5R air intake systems include Pro 5R filters with factory-oiled 5-layer, progressively finer, cotton gauze media. The progressive layering allows the filters to flow at high levels, even when dirty. They have been tested at 98.6 percent filtration efficiency and are washable and reusable for long life. The Super Stock systems with Silver Bullet throttle body spacers feature aFe's Serrated/Helix combination design that creates intake turbulence in the combustion chamber to increase horsepower, torque, and improved throttle response. The Serrated/Helix combination design also reduces the intake whistle of competitor's helix-only designs. The throttle body spacers are precision-machined from 6061 T-6 billet aluminum for light weight, high-strength, and a perfect fit and finish. The intake tubes are mandrel-bent with durable black powdercoating for increased airflow, improved volumetric efficiency, and better performance. The clamps, couplings, and hardware are included with these direct bolt-on kits, no cutting or drilling is required to provide a hassle-free installation.
