Hot Side Intercooler Tube

The hot side tube is a critical component often neglected in stock configurations. The factory routing can lead to premature failure due to contact with the power steering line, causing boost leaks and power loss. HSP Diesel has engineered a solution that routes the hot side tube directly into the intercooler, promoting better airflow and lower temperatures while ensuring ample clearance in tight spaces. Made from a 3-inch mandrel-bent tube, it can be powder-coated for a customized engine bay appearance.

Cold Side Tube

Similarly, the cold side tube, also crafted from a 3-inch diameter mandrel-bent design, maximizes air flow and minimizes turbulence. It connects seamlessly to the factory-style bridge, ensuring optimal efficiency and performance without sacrificing compatibility with existing components.
