Momentum HD Aluminum Black Cold Air Intake System with Pro Dry S Filter (51 72001) by aFe. Bringing you the next generation of intakes, the Momentum HD sealed air intake system is superior in every way. From the one piece sealed housing with a built in sight window, to the massive 1,000 cfm air filter and premium hardware. If you're on a budget or don't have a lot of time to work on your vehicle, don't think you have to forget about getting more performance or fuel mileage from your car or truck. The aFe Momentum Cold Air Intake System is inexpensive and can be installed in an hour or less with simple hand tools. This system replaces your factory air filter and airbox with your choice of aFe performance air filter and a one piece open element airbox heat shield that seals against the hood, isolating the filter from engine heat. The increased flow of cooler air to your engine will result in noticeable gains in power and performance. Cooler, denser air contains more oxygen, and more oxygen in your engine's air intake charge means better combustion, resulting in greater engine output. The one piece airbox heat shield is made of rugged 16 gauge powder coated steel. It installs easily in place of the factory airbox; no cutting or drilling is required. The box shield is attached with quality stainless steel hardware that is supplied with the kit. A specially developed 3 angle velocity stack smoothes the airflow transition from the air filter to the intake tube. Top quality, flexible rubber trim at the top of the box shield seals against the hood when it is closed, shielding the air filter from engine heat and allowing it to take in cooler air. Some systems include a powder coated steel or brushed aluminum cover to further shield the filter. The aFe Momentum Air Intake System comes complete with everything necessary for installation, including comprehensive instructions. It's backed by aFe's limited 2 year warranty and made in the USA. aFe (Advanced Flow Engineering, Inc.) manufactures performance products for late model cars, light trucks and SUVs.
