3Inside The Kit
4The 107% Larger Cooling System
F-150s pull boats, tow trailers, and live in heat. The 705HP kit ships with a low-temperature radiator that’s 107% larger than the previous-generation Roush F-150 SC — literally double the cooling capacity. Combined with high-flow Bosch PCE pump and custom degas bottle, the system holds intercooler temps flat on towing pulls, sustained highway speeds, and back-to-back full-throttle runs. Colder-heat-range Ford Performance spark plugs are reduced-gap to manage forced-induction combustion. The whole system is built to dyno-test cycles measured in days, not minutes.
5Install + Tuning
Calibration: Roush RDT (Roush Diagnostic Tuning) software delivers the supplied flash. 93-octane premium fuel optimized (91 compatible). All wiring plug-and-play, all hoses custom-formed for the F-150 engine bay. Vehicle max speed is unchanged from production configuration. Warranty: 3-year / 36,000-mile limited powertrain warranty when installed by an ASE-certified technician. Cold-start tested to -20°F. 900+ hours of dyno endurance testing.
