HSP Diesel Intercooler Bundle Kit (Part No: 292-HSP) for 2004.5-2005 LLY Duramax

If you're looking to kick off your performance upgrades on your 2004.5-2005 LLY Duramax Chevrolet or GMC truck, the HSP Diesel Intercooler Bundle Kit is your best bet. This kit is designed specifically for those who want to enhance their truck's capabilities, replace failing stock parts, or simply add a splash of color to the engine bay.

Why Choose the HSP Intercooler Bundle Kit?

This kit is an essential first step for any LLY Duramax owner. Whether your goal is to boost performance or improve reliability, the HSP Intercooler Bundle Kit provides a solid foundation. It’s engineered to address common weaknesses in the factory setup and optimize airflow for better overall efficiency.

Hot Side Intercooler Tube

The hot side tube included in this kit is a game changer. The factory hot side pipe on LLY trucks is notorious for failure due to its routing, which often rubs against the power steering line. This can lead to boost leaks and a noticeable drop in power.

HSP Diesel has designed a hot side tube that routes directly into the intercooler, minimizing these issues. Constructed from a 3-inch mandrel-bent tube, this upgrade not only enhances airflow but also lowers temperatures, ensuring your engine runs more efficiently. Plus, you can choose a powder-coated finish to brighten up your engine bay!

Cold Side Tube

Just like the hot side, the cold side tube is crafted from a 3-inch diameter mandrel-bent tube, designed for maximum airflow and reduced turbulence. This ensures that your truck can maintain optimal performance while connecting seamlessly to the factory-style bridge. It's the perfect complement to your hot side upgrade.
