The Edelbrock Pro Tuner Supercharger System #15899 is designed for a large group of model-years that include the 2015-20 Ford Mustang GT, GT350 and Bullitt edition Mustangs. This special kit is intended for competition applications and features the modular supercharger inlet that allows the use of larger throttle bodies. Included is Edelbrock’s high-flow Competition Air Intake System with reusable filter element and 113mm MAF housing, a 6-rib belt drive system, and all vehicle-specific installation components. Items that are not included in this system are the supercharger pulley (6- and 8-rib options are sold separately), the supercharger belt, fuel pump and injectors, spark plugs, and coil covers (#41149 sold separately). An optional 8-rib belt drive assembly for high-horsepower engines is available under part number 15879. Use of this system on 2015-17 Mustang GT and 2016-19 GT350 models requires the Edelbrock 103mm Throttle Body #38988, sold separately. Use on 2018-20 Mustang GT and Bullitt models will require Edelbrock 103mm Throttle Body #38989, also sold separately. The Pro Tuner Supercharger System #15899 is capable of delivering horsepower output well over the 1,000 mark with the appropriate supporting modifications and custom tuning (not provided by Edelbrock).
