3rd Gen 5.9L Cummins Air Intakes

Maximize airflow, lower exhaust gas temperatures (EGTs), and unlock hidden horsepower and torque on your 2003–2007 3rd Gen 5.9L Cummins with a high-performance cold air intake system. Factory air boxes and restrictive paper filters choke the turbocharger, limiting engine efficiency under heavy towing and high-boost conditions. Upgrading to an open-element or sealed cold air intake featuring high-flow washable filters and smooth-walled intake piping delivers denser air charges and improved throttle response. Shop top-tier air intake systems engineered for exact factory fitment and extreme-duty durability.
