ProCharger High Output Intercooled Systems

The HO Intercooled Intercooled systems utilize the patented, proven and self-contained P-1SC ProCharger, a compact supercharger drive system, a highly-effective, air-to-air intercooler, OEM-quality mounting brackets, fuel system upgrade (FMU and pump), ProFlo anti-surge / bypass valve, tuning and all necessary supercharger and intercooler tubes for installation onto your GM truck and SUV engine. ProCharger HO Systems come standard with a 2 core intercooler; the larger 3 core intercooler is an optional upgrade.

ProCharger supercharger systems feature easy installation, minimal relocation of components, no need for external oil feed and return lines and avoids having to deal the complexity and maintenance issues of an air-to-water-to-air intercooler configuration. ProCharger systems for GM trucks and SUVs feature a visually appealing, “from the factory” look and come with a standard 3-year warranty on the intercooler and 1-year warranty on the supercharger (Optional 3-year supercharger warranty is available).
