Description
Take your 2011-2014 Ford Mustang GT 5.0L equipped with an Edelbrock 1588 or 15880 Supercharger to the next level with the Edelbrock Stage II Upgrade Kit #15882. Designed for racing applications only, this kit boosts performance by providing a smaller 3.25" supercharger pulley, a high-flow competition air intake system, and a Gatorback belt for increased boost levels and improved throttle response.
