2003-2004 Ram 2500/3500 5.9L Cummins Cold Air Intakes

The factory intake on your 2003-2004 Ram 2500/3500 is sufficient for everyday use, but it falls short for heavy-duty tasks like towing and off-roading. Upgrade to an aftermarket cold air intake to improve airflow, boost power, and enhance fuel efficiency. Additionally, many cold air intakes give your diesel engine a more aggressive sound. Pair your cold air intake with an upgraded Exhaust System for even greater performance! Ram Cummins Fitments: 2003, 2004 Ram 5.9L Cummins. Submodel Fitments: Tradesman, Laramie, Laramie Longhorn, Big Horn, Limited, Lone Star, Power Wagon. Some exceptions apply, please see individual product pages for specific fitments.
