ProCharger Stage II Intercooled Systems and Tuner Kits

When compared to the HO System components, the new Stage II System and Tuner Kit utilize a larger, front mounted intercooler, fabricated coolant tank, specially-designed radiator fan shroud assembly and a larger air filter. Installation of the Stage II components requires minor trimming to the inside of the stock lower front bumper cover (factory engine cover does not require modification or trimming). 

The Intercooled Stage II Tuner Kit is identical to the complete system, but omits fuel injectors and computer programming. Higher boost and power levels are available for modified engines.
