The GMC Sierra 3500 Intercooler Piping by Sinister Diesel is a robust, high-performance upgrade designed specifically for the `01-`05 Duramax 6.6L models. Crafted with precision, this upper radiator pipe is made from premium 6061 aluminum and boasts a striking Sinister Blue finish.

Engineered to stand the test of time, this radiator pipe kit is your solution for enhancing the reliability and durability of your vehicle's cooling system. The coolant hoses that come standard in factory models are susceptible to wear and tear, risking cooling system failures. However, Sinister Diesel’s piping, with its abrasion- and crack-resistant aluminum construction, ensures a reliable performance for years. The precision mandrel bent tubing guarantees a flawless fit, reducing the risk of unexpected downtimes and providing the needed protection for your GM Duramax engine. Its stylish powder-coated blue finish not only protects but subtly enhances the engine bay. Each silicone boot is marked with the Sinister Diesel logo and is built to withstand heat and high pressure, rated up to 400psi, assuring longevity and resilience.
