MAGNUM FORCE STAGE 1 COLD AIR INTAKE SYSTEM WITH RE-WASHABLE, REUSABLE & REOILABLE PRO 5R FILTER Replaces factory air box and stock air filter Improves airflow up to 75%, throttle response, acceleration and fuel efficiency Increases up to 60 ft-lbs of torque-up to 50 HP gain! More air equals more power! For the automotive enthusiast who wants all the power and torque he can get! Compared to our other systems, the Magnum FORCE Stage 1 intake system replaces the entire stock air induction system. Remembering our motto Stock Sucks, we eliminate the stock air box, the stock air filter and the stock intake tract. The only thing retained is the stock electronics. We make sure that our Stage 1 system, like all our intake systems, works with the stock electronics. Cold air equals more power! In designing out the stock air box, we design in the largest air box that we can for each vehicle application. Even though we make it as large as possible, we are careful to use the stock mounting points. There is no need to cut or drill anything when you install our system. We make the air box as large as possible so that we can get the largest air filter. At first glance you probably won't notice the unique features that we design into each air box. Each of them is there for a purpose, either to make your job of installing the system easier or to improve the performance of your vehicle. Here are a few the features and benefits that distinguish aFe's Magnum FORCE Stage 1 intake systems: 16-gauge powder-coated steel for a durable, OE look and finish Trim sealed or covered-seals out hot engine airSecured PEM-nuts for easier installationWelded and preassembled sheet metal for faster installationPre-positioned opening for stock attachments-no dangling wires, relocating hoses or tubes By designing the largest filter for the largest air box, we are able insure that the vehicle is getting the maximum amount of air regardless of the performance upgrades. System uses our conical universal clamp-on filters.Here are some common characteristics of our Pro 5R air filters: 100% poly urethane construction-durable, resistant to high temperature and chemicals5 layers of progressively finer medical grade cotton gauze Deep pleats for greater flow and dust holding capacityRounded pleat geometry for better airflow characteristicsFull or modified velocity stack for better airflow characteristicsWashable/reusable filter media for longer service lifeRe oil with our restore kit sold separately (22441G). This Stage 1 Kit reuses the stock intake tube for an economical way to increase air flow horsepower and torque...not as much as Stage 2 (sold separately, 22438G).
