2003-2004 Silverado/Sierra 2500/3500 Cold Side Tube – Factory Style Kingsport Grey

The LB7 Duramax has a very restricted charge air system from the factory. After realizing the potential power loss from the small-diameter factory tubes, we increased the size of the tubing to 3 Inch which proved major power gains over the factory intercooler system. While dyno testing the HSP upgraded intercooler tubing, we saw incredible horsepower and torque gains from such an overlooked component. Power increases will fluctuate between models due to tuning calibrations, turbo options, and aftermarket fuel systems. One thing to be sure of though, you will only be able to move as much air as your intercooler system will flow. So, be sure to use the HSP upgraded charge tubes to maximize the potential of your truck.
