Improve intake flow on your 2011-2016 LML Duramax with the Dirty Diesel Customs Dirty Cold Side Crossover Pipe. This kit is a precision-engineered solution designed to replace the restrictive OEM intake on your diesel engine running with 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 also 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 both 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.
