It comes with a new 85mm S/C Pulley, Shorter FEAD Belt, Cold Air Induction System, ROUSH Flash Voucher card and Installation Instructions.Hundreds of hours of research and testing go into the development of the ROUSH superchargers including testing in extreme environmental temperatures from -20 degrees up to and through 120 degrees Fahrenheit and at higher altitudes of 14,000 ft for quality and performance. Over 40 emissions tests to ensure that the Mustang still makes the same emissions and that all the Ford engine diagnostics functions as intended but this kit is currently not CARB approved. Engine dynamometer development allows for the re-map camshaft positions and many other aspects of the calibration.
