The HSP Hot Side Intercooler Tube, also known as the 000-HSP, is a proven upgrade for 2004.5-2010 Chevrolet Silverado and GMC Sierra trucks equipped with the 6.6L Duramax LLY, LBZ, or LMM engine.

Whether your truck is stock, modified, daily driven, used for towing, or part of a full performance build, the HSP Hot Side Intercooler Tube improves airflow, reliability, sound, and the overall appearance of your engine bay.

Why Upgrade the Factory Hot Side Intercooler Tube?
The factory hot side intercooler tube gets the job done, but its restrictive bends and factory-style connections leave room for improvement. The factory design can create unnecessary turbulence within the charge-air system, while the lower intercooler boot can become a potential failure point as boost pressure and engine performance increase.

HSP Diesel designed the 000-HSP Hot Side Intercooler Tube to provide smoother airflow, stronger connections, and a cleaner finished appearance under the hood.

What Makes the HSP Hot Side Intercooler Tube Different?
The HSP Hot Side Intercooler Tube is manufactured from 3-inch mandrel-bent tubing. Its smooth, sweeping bends help reduce turbulence and improve airflow by up to 40 percent compared to the factory-style piping.

The straight-style connection at the intercooler also eliminates the weak, failure-prone factory lower intercooler boot configuration. Removing this common failure point creates a stronger and more reliable connection for both stock and modified trucks.

Along with improved airflow and reliability, many customers notice a cleaner and more distinct engine and turbo sound after installation. The tube is also available in multiple powder coat options, including custom colors, allowing you to complete the look of your engine bay.
