Overview

The HSP Intercooler Bundle Kit is specifically designed for the 2004.5–2005 LLY Duramax Chevrolet and GMC Trucks. This kit is a crucial upgrade for those looking to enhance their vehicle's performance, reliability, and aesthetic appeal. By replacing subpar factory components, the HSP Intercooler Bundle Kit not only boosts airflow but also lowers intake temperatures, ensuring your engine runs efficiently under load.

What is the HSP Intercooler Bundle Kit?

This bundle serves as an excellent entry point for modifications, catering to a wide range of enthusiasts—whether you're upgrading for performance, replacing worn-out parts, or simply looking to add a splash of color to your engine bay.

Hot Side Intercooler Tube

The Hot Side Tube included in the HSP Intercooler Bundle Kit addresses a common failure point in the factory setup. The original routing can result in the tube rubbing against the power steering line, leading to boost leaks and a noticeable drop in power. HSP Diesel has engineered a solution that routes the hot side tube directly into the intercooler, improving airflow and reducing temperatures. Crafted from a 3-inch mandrel-bent tube, it can also be powder-coated for a personalized touch in your engine bay.

Cold Side Tube

The Cold Side Tube complements the hot side with its own 3-inch diameter, designed to maximize air flow while minimizing turbulence. The mandrel-bent design ensures a smooth transition and connects seamlessly to the factory-style bridge, maintaining efficiency and performance without sacrificing essential components.
