HPF STAGE 4 | 430KW

300 6.4L | HPF STAGE 4 | 430KW

The Chrysler 300C 6.4L Stage 4 upgrade starts with our trained technician removing the engine from the vehicle and disassembling it to replace the factory camshaft with a high performance camshaft and fit a phase limiter kit. We also fit a set of Higgins Performace CNC ported cylinder heads. We then replace the MDS Lifters with Hellcat units and fit upgraded valve springs to the cylinder heads and reassemble the engine with new head gaskets and head bolts.

We then fit a high flow K&N cold air intake system which outflows the standard air intake by around 35%, 4-1 stainless steel extractors, high flow metallic cats & a dual 3" stainless steel catback exhaust to increase the engine's breathing capabilities.

We then custom tune your vehicle's ECU on the dyno utilizing the latest ECU tuning software to maximize power and fuel efficiency. We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicle's performance and driveability. This is all completed in a week and at the end of this upgrade you will provided with a dyno graph detailing the power & torque increase of your vehicle.
