Upgrade the airflow and performance of your 2011–2016 Duramax LML with an aFe Power Cold Air Intake System. Designed to increase airflow, improve throttle response, and boost horsepower and torque, these intake systems significantly outperform the restrictive factory air box while maintaining excellent filtration and engine protection. Many aFe intake systems can outflow the factory intake by a large margin and provide noticeable performance gains and improved engine efficiency.
aFe offers multiple intake styles for the LML Duramax including Magnum Force Stage-2, Momentum HD sealed intake systems, and Quantum intake systems. The different options mainly vary by intake housing design and filter type (dry filter or oiled performance filter), allowing you to choose the best setup for daily driving, towing, or performance applications.
These systems feature high-flow washable and reusable filters, roto-molded intake tubes for improved airflow, and direct bolt-on installation using factory mounting locations for a quick and easy install.
