aFe is proud to introduce the all new stage-2 intake system for the 2013-2014 RAM diesel trucks with the L6-6.7L turbo diesel engine. In recent testing this system outflowed the factory intake by 113 percent . This highly engineered system uses a powder-coated heat-shielded air box with a one-piece intake tube. Handling filtration duties is the PRO DRY S performance air filter that features 3-layers of synthetic oil-free media. The PRO DRY S filter is constructed with 100 percent polyurethane for long life and multiple cleaning cycles. The heat-insulating, molded plastic intake tube adapts to the stock intake elbow making it easier for installation. The tube is also engineered for improved volumetric efficiency and maximum performance while lowering Intake Air Temps (I.A.T.). One Piece Powder-Coated Steel Heatshield: A one-piece powder-coated steel heatshield is used to keep the air intake charge cool and dense. Designed to bolt directly to the bottom half of the stock air box, the heatshield incorporates the use of the factory RAM active air. Huge 5 inch Flange 360 Degree Air Filter: A huge inverted cone 360 degree radial flow air filter is used for maximum filtration (99.2 percent efficient) and convenience (requires no oils to clean). The PRO DRY S performance air filter features 3-layers of synthetic oil-free media and is constructed with 100 percent polyurethane for long life and multiple cleaning cycles. Rotomolded Tube: Rotomolded intake tube is engineered for improved volumetric efficiency and maximum performance while lowering Intake Air Temps (I.A.T.). The tube connects to the stock intake elbow for added convenience and quicker installation. Hassle-Free Installation: aFe has developed this intake to provide a hassle-free installation that utilizes all factory mounting locations minimizing the use of unnecessary hardware. Legal in California only for racing vehicles which may never be used upon a highway.
