Product Description

The Roush 422001 Phase 2 supercharger kit transforms a 2015-2017 Mustang GT into a 727-horsepower street monster. Featuring the R2300 TVS roots-type blower mounted to a large aluminum intercooler with dedicated radiator and degas tank, the system ensures consistent cool charge and performance. Roush's plug-and-play tuning via the Roush Diagnostic Tool ensures seamless calibration, no lift protection, and maintains 50-state street legality for 2015-2016 models.

Complete with high-flow intake hardware, fuel injectors, and premium spark plugs, the kit is backed by a 3-year/36,000-mile parts warranty. Installation requires moderate mechanical skill (~20 hours), and Eaton's TVS architecture delivers smooth, responsive boost throughout the RPM range--transforming the Coyote's power curve without compromising drivability.
