2011-2016 LML Duramax Dirty Intercooler Piping Kit (LML-INT-A103-0527)

Fits

NOTE: The Throttle Valve Off Option will delete the Grid Heater. If you select this option you will also require custom tuning.

Improve the airflow of your 2011-2016 LML Duramax with our Dirty LML piping kit. This comprehensive package is designed to replace restrictive OEM components with precision-engineered parts that optimize airflow, reduce inefficiencies, and look damn good while doing it.

Cold Side Crossover Pipe

Features a smooth interior finish and circular cross-section for superior airflow dynamics compared to stock. A four-axis CNC-machined flange ensures seamless transitions into the intake plenum, reducing turbulence and improving performance. For those ditching the throttle valve, the kit further minimizes restrictions by eliminating the grid heater and throttle valve assembly. 

Passenger-Side Intercooler Pipe

This oversized 3.5" pipe (vs. the failure-prone 3" OEM version) delivers smoother airflow, greater durability, and precision fitment. Say goodbye to weak spots and airflow bottlenecks.

Driver's-Side Intercooler Pipe 

A durable two-piece design made to make installation significantly easier in a tight engine bay.  

Built to Last

Built from 6061 aluminum, TIG welded, and powder coated in-house, this kit is durable and visually impressive. This kit replaces the OEM Clip Ring Design with high-quality silicone boots and stainless steel T-bolt clamps for improved sealing and the ability to hold higher boost pressures without leaking. Whether you're upgrading for performance, reliability, or aesthetics, this kit is built to meet your needs while allowing flexibility for further modifications.
