The P-1SC-1 is an internally lubricated centrifugal supercharger system that's driven by a 6-rib belt and is cable of dumping enough spare boost into your Raptor's big 5.4L motor to meet just about any application or performance need. Each of these intercooled kits comes standard with a three-core air-to-air intercooler that's mounted toward the front of your engine bay to provide as much cooling as possible. Each ProCharger intercooled supercharger kit for the 5.4L Raptors comes with installation hardware and instructions to help you get your potent Raptor build out on the street or trail in almost no time at all.
