If you're looking to give your 2004.5 or 2005 LLY Duramax a solid boost, the 292-HSP Intercooler Bundle Kit is where you should start. This kit isn't just another aftermarket part; it's a game-changer for anyone serious about performance. Whether you're trying to replace those failing stock components or just want to add a splash of color to your engine bay, this bundle has got you covered.

So, what's in the HSP Intercooler Bundle Kit?

Think of this as your entry point into the world of serious modifications. The kit includes everything you need to get your intercooler setup running smoothly. It’s designed for both the everyday driver and the performance junkie. The whole idea is to enhance your truck’s performance while keeping it easy to install and maintain.

Hot Side Intercooler Tube

Let’s talk about the hot side tube. This is one of those parts that often gets overlooked, but trust me, it's vital. The stock hot side pipe on the LLY trucks has a notorious reputation for failing, mainly because it rubs against the power steering line, leading to leaks and power loss. HSP Diesel recognized this issue and designed a hot side tube that routes directly into the intercooler, which means better airflow, lower temperatures, and more clearance in those cramped spaces. Made from a durable 3-inch mandrel-bent tube, you can even get it powder-coated to match your style.

Cold Side Tube

Now, onto the cold side tube. This piece is also made from a 3-inch mandrel-bent tube, which is crucial for maximizing airflow and minimizing turbulence. It connects seamlessly to the factory-style bridge, ensuring that you’re not sacrificing performance for compatibility. This design keeps everything running efficiently while giving you the power boost you’re after.

Compatibility

Wondering if this kit fits your ride? It’s designed specifically for the LLY Duramax from 2004.5 to 2005, and it’s a perfect match for VIN Code 2. Just check the 8th character of your VIN to confirm.
