2011-2016 Duramax LML Dirty Diesel Cold Side Crossover Pipe (LML-INT-A027)
Improve intake flow on your 2011-2016 LML Duramax with the Dirty Cold Side Crossover Pipe. This precision-engineered solution replaces the restrictive OEM intake on your diesel engine and is designed for trucks running without a throttle valve. By eliminating the rough, inefficient cast aluminum intake, this kit improves airflow and reduces unnecessary restrictions, optimizing efficiency.
Its smooth interior finish and circular cross-section ensure better flow dynamics over stock, while the four-axis CNC-machined flange transitions airflow seamlessly into the intake plenum. This design not only enhances performance but simplifies the upgrade process with adaptability to both OEM and aftermarket intercooler piping.
Built from 6061 aluminum, TIG welded, and powder coated in-house, this kit is durable and visually impressive. Whether you're upgrading for performance, reliability, or aesthetics, this kit is built to meet your needs while allowing flexibility for further modifications.
