2003-2004 Duramax Cold Side Tube (Factory Style) (105-HSP)

Fits

From the factory, the LBZ Duramax has a very restricted charge air system. After realizing the potential power loss from the small-diameter factory tubes, HSP increased the size of the tubing to 3" which proved massive power gains over the factory intercooler system.

While dyno testing the HSP upgraded intercooler tubing saw incredible HP and torque improvements from such an overlooked component. This Tube will flow much more than the factory unit. Power increases will fluctuate between models due to tuning calibrations, turbo options, and aftermarket fuel systems.
