Part Number: 292-HSP

What Is the HSP Intercooler Bundle Kit for the LLY Duramax?

This kit is a great first upgrade—whether youre replacing failing factory parts, boosting performance, or adding a pop of color under the hood. Its made to work for every type of build, no matter your goals.

Hot Side Intercooler Tube

The factory hot side pipe on LLY trucks is a known failure point due to its routing against the power steering line, which can eventually rub through and cause a boost leak. HSPs upgraded design reroutes directly into the intercooler to improve airflow, reduce temps, and add clearance. Constructed from a 3" mandrel-bent tube, it's available in various powder coat finishes to upgrade your engine bays appearance.

Cold Side Intercooler Tube

The 3" mandrel-bent cold side tube is optimized for maximum airflow and minimal turbulence. It connects to the factory-style bridge for superior efficiency, flow, and performance—while retaining all necessary OEM components.
