The 292-HSP or best known as the Intercooler Bundle Kit For the 2004.5 and 2005 LLY Duramax Chevrolet and GMC Trucks. The Intercooler Bundle Kit is one of the best places to start when it comes to modifying your LLY Duramax.
The HSP Intercooler Bundle Kit is a kit that we like to think of as a great first step. This bundle is made with everyone in mind no matter what your goals or next step is going to be. Whether you are looking to increase performance, change out failing stock parts, or just need to spice up your engine bay with some color the Intercooler Bundle Kit is a great place to start.
The hot side tube that is inside the HSP Intercooler Bundle Kit is a part that is often overlooked. The hotside pipe that comes from the factory on the LLY trucks is often known to fail. The factory routing that it takes rubs on the power steering line, this causes the line to create a hole in the tube resulting in a boost leak and loss of power. From day one this is a problem and HSP Diesel knows that it can be a big one with no notice. This is why our Hot Side tube routes directly into the intercooler, this results in lower temperatures, better airflow, and the added clearance in those tight places. The Hot side intercooler tube is made from a 3 Inch mandrel-bent tube that can be powder coated to spice up the engine bay.
The Cold side pipe is also made of a 3 Inch diameter tube. We mandrel-bent the tube to give the maximum flow of air and decrease the turbulence that is often seen inside these pipes. The mandrel-bent 3 Inch cold side tube connects to the factory style bridge for the ultimate efficiency, flow, and maximum performance capabilities of your truck while retaining all the necessary parts.
LLY: 04.5-05 VIN Code 2
Engine code is dictated by the 8th character of the VIN number. The 10th character is the year of the truck.
This kit is best suited for factory or drop-in replacement chargers, as it resembles the factory intercooler routing.
