Hot Side Intercooler Tube

The hot side intercooler tube is a critical component often overlooked by many truck owners. The factory version on LLY trucks is notorious for failing due to its poor routing, which can rub against the power steering line and create a boost leak, resulting in a noticeable loss of power. HSP Diesel has designed their hot side tube to route directly into the intercooler, which improves airflow and reduces temperatures while providing additional clearance in tight spaces. Constructed from a durable 3-inch mandrel-bent tube, it can also be powder-coated to enhance your engine bay's aesthetics.

Cold Side Intercooler Tube

Just like the hot side, the cold side tube is made from a 3-inch diameter mandrel-bent tube that maximizes airflow and minimizes turbulence. This design ensures that you get the best performance possible while maintaining compatibility with the factory-style bridge. It's engineered for optimal efficiency and flow, making it a perfect match for your LLY Duramax.
