New Intercooled ProCharger systems for the Hummer H2 produce a 55-75% power gain on stock motors running pump gas, and typically improve gas mileage as well. These systems are 100% complete bolt-ons, and deliver the coolest charge air temperatures available, for maximum engine longevity as well as power. Standard equipment includes an air-to-air intercooler system and a self-contained, gear-driven supercharger available with a 3-year supercharger warranty. Installation is very straightforward, with no accessory relocation, and can be completed in approximately 8-10 hours.

The ProCharger models in these systems feature ATI’s patented self-contained oiling technology, which delivers cooler operating temperatures and eliminates the need to punch a hole in the oil pan. The self-contained ProChargers are paired with a highly effective air-to-air intercooler, which together produce 7-8 psi of intercooled boost in the HO Intercooled System, or 10-11 psi of boost in the Stage II Intercooled system. Due to the tremendous positive impact of intercooling upon both power gains and engine longevity, only intercooled ProCharger systems are being offered for the H2.
