The Wehrli 4" intake kit for 2003–2007 Dodge Ram 2500/3500 5.9L Cummins replaces restrictive factory intake plumbing with a fabricated aluminum 4" pipe and dry filter assembly. It increases intake flow and responsiveness, uses smooth aerodynamic bends, includes silicone boots, clamps and hardware, and ships with a dry air filter plus hydrophobic pre-filter cover and powder-coat finish options.
