Hot Side Intercooler Tube

The hot side tube is a critical component that often gets overlooked. The stock hot side pipe on LLY trucks has a notorious reputation for failure due to its routing, which can rub against the power steering line. This can lead to boost leaks and a noticeable drop in performance. HSP Diesel has addressed this issue by designing a hot side tube that routes directly into the intercooler, ensuring lower temperatures and improved airflow. Constructed from a durable 3-inch mandrel-bent tube, it can also be powder-coated to add some flair to your engine bay.

Cold Side Intercooler Tube

Just like the hot side, the cold side tube is made from a 3-inch mandrel-bent design, allowing for maximum airflow and reduced turbulence. This component connects seamlessly to the factory-style bridge, ensuring optimal efficiency and performance without sacrificing any necessary parts.
