This Magnum FORCE Stage-2 air intake system uses a 3-1/2in diameter black powder-coated aluminum tube with a massive 5-1/2inPro DRY S air filter for maximum performance. The simple snap-in housing utilizes the factory lower air box for an easy installation. The 3-angle adaptor speeds up the air flow after the air filter for improved performance and throttle response. All of these combine this kit produces 18 max horsepower, 23 lbs. x ft. torque and out-flowed the factory intake by 27%. This intake replaces the factory intake box and reuses the factory inlet tube. All hardware and components are included for a hassle-free installation.
