What Is the Intercooler Charge Pipe Bundle for the LML?
The LML Duramax platform is extremely capable”but often limited by restrictive or failure-prone factory parts. HSP Diesel created this kit to replace the major weak points and unlock your trucks true potential in one streamlined bundle.

Hot Side Tube
The OEM hot side pipe uses a two-piece design that is known to fail. HSPs upgraded version features a single-piece, mandrel-bent 3" aluminum pipe with high-strength silicone boots on both ends. The result: improved airflow (up to 40%) and durability.

Cold Side Tube
Although less likely to fail, the factory cold side pipe still poses a restriction. HSPs 3" mandrel-bent upgrade reduces turbulence and improves charge air flow”especially when paired with the Max Flow Bridge and VGT Mouthpiece in this kit.

Max Flow Bridge
This two-piece CNC-machined bridge uses an O-ring-sealed center to virtually eliminate boost leaks. Designed for seamless fitment and maximum airflow, it completes the cold side system while offering reliability and easy installation.

VGT Intake Mouthpiece
Hand-fabricated with optimized bends and transitions, this intake mouthpiece improves turbo efficiency by reducing turbulence and increasing flow into the compressor housing.
