GDP Hot Side Intercooler Tube (2011-2016 6.6L Duramax LML)

The GDP hot side intercooler tube increases performance and flow up to 40% over stock. Constructed from 3" mandrel bent tubing for smooth, sweeping bends, and proper fitment. The GDP hot side intercooler tube eliminates the weak, and prone to fail factory lower intercooler boot. Our design allows for a straight connection to the intercooler, eliminating any issues with the silicone boot. You will also notice a crisper engine and turbocharger tone.
