Hot Side Intercooler Tube: The Overlooked Upgrade

The factory hot side tube on LLY Duramax trucks is notorious for failure. Its routing often leads to contact with the power steering line, which can create a hole in the tube, resulting in boost leaks and a noticeable drop in power. The HSP hot side tube addresses this issue by routing directly into the intercooler, improving airflow and lowering temperatures. Crafted from a 3-inch mandrel-bent tube, it's not only functional but can also be powder-coated to add some flair to your engine bay.

Cold Side Tube: Maximum Airflow and Efficiency

Equipped with a 3-inch mandrel-bent cold side tube, this kit minimizes turbulence and maximizes airflow. It connects seamlessly to the factory-style bridge, ensuring that you maintain optimal performance without sacrificing any necessary components. This attention to detail allows for enhanced efficiency and flow, making it a perfect fit for your LLY Duramax.
