aFe Momentum HD cold air intake system with a one-piece sealed XLPE housing that uses the factory air scoop inlets, a clear sight window and an optional auxiliary inlet. A dyno-tuned XLPE intake tube feeds a 9 in tall radial flow Pro DRY S filter on a 5-1/2 in flange with an inverted top. The Pro DRY S filter uses three layers of oil-free synthetic media and is washable and reusable. It flows 585 CFM at 7 in H2O, 56% more than the factory intake, and is rated at up to 15 hp and 27 lb-ft. The filter can be removed for service by taking out only the intake tube.
