The HSP Intercooler Bundle Kit for LLY Duramax Trucks

Introducing the 292-HSP, commonly known as the Intercooler Bundle Kit, designed specifically for the 2004.5 and 2005 LLY Duramax Chevrolet and GMC Trucks. If you're looking to modify your LLY Duramax, this kit is an excellent starting point!

What is the HSP Intercooler Bundle Kit?

The HSP Intercooler Bundle Kit is like the first step on your performance journey. It’s crafted with a variety of enthusiasts in mind—whether you’re aiming to boost performance, replace worn-out stock parts, or just want to add a splash of color to your engine bay, this kit has you covered.

Hot Side Intercooler Tube: What’s the Deal?

Let’s talk about the hot side intercooler tube included in the HSP Intercooler Bundle Kit. This component often gets overlooked, but it plays a crucial role. The factory hot side pipe on LLY trucks has a reputation for failing due to its routing, which tends to rub against the power steering line. This can create a hole in the tube, leading to a boost leak and a noticeable drop in power—a problem that’s been around since day one.

That’s why our Hot Side tube is designed to route directly into the intercooler. This design helps lower temperatures, improve airflow, and provides extra clearance in those tight spots. Made from a sturdy 3-inch mandrel-bent tube, you can even choose to powder coat it for that extra flair in your engine bay.

Cold Side Tube: What You Need to Know

The cold side pipe is also crafted from a 3-inch diameter tube, and like the hot side, it’s mandrel-bent to maximize airflow and minimize turbulence. This ensures that you get the best performance possible.

The mandrel-bent 3-inch cold side tube connects seamlessly to the factory-style bridge, ensuring optimal efficiency and flow while keeping all the necessary components intact.
