Based on the design of the C6 HO Intercooled system and ProCharger C5 race kit, the new Stage II Intercooled ProCharger system substantially raises the bar for C5 performance. The rugged new bracket design shows more of the supercharger for a better appearance, produces the industry’s greatest belt wrap, and allows belt replacement without removing the supercharger. A larger, highly effective 4.5” twin highflow intercooler system with 3” tubing is standard, as is a new, higher flowing air inlet system. And unlike others, not only is all the hardware of OEM quality, a new radiator cradle is supplied to avoid cutting into the stock vehicle. Furthermore, an industry exclusive 3 year warranty is available up to 9 psi.
