Designed to work with either the original air box or the Airaid Intake System, AirAid’s 300-928 Modular Intake Tube (M.I.T.) for the 03-07 Dodge Ram Cummins Diesel will wake up even the tamest of engines. This is possible because the M.I.T. flows 20% more air than the factory unit. The M.I.T. is constructed of cross-linked high-density polyethylene for strength and durability. All M.I.T. kits come complete with all the mounting hardware needed. Like the AIRAID Intake Systems, they bolt right on in minutes with simple hand tools.
