Edelbrock part #41137 aluminum coil covers are designed for 2015-17 Mustang GT 5.0L with the DP-3C Edelbrock supercharger. Our kit is geared towards those with competition versions of the supercharger kits, which do not include coil covers, but would like to add them. Covers are designed to fit around the supercharger unit and will not fit naturally aspirated motors.
