Roush 421994
The ROUSH Phase 2 supercharger upgrade kit builds on the outstanding performance of our 2015-2017 Phase 1 supercharger system by adding proven core components and careful calibration, for an additional 57 horsepower and 65 lb-ft of torque. The result is an outstanding 727 hp / 610 lb-ft of torque while retaining the daily confidence you expect from the engineering of ROUSH Performance. ROUSH engineers spend hundreds of hours in the laboratory, on the dyno, and out in the field to ensure the components and calibration deliver consistent performance in all conditions.
