The Pulley should be added along with supercharger porting and Performance Exhaust for a big performance kick. Your car will still retain the factory belt and "NO Modifications" to the blower are required for installation.
Fits all Jaguar XJR, XKR, S-Type R with the 4.0L & 4.2L.
Fits Land Rover Range Rover and Range Rover Sport with the 4.2L
*No ECU Tuning is required for this Supercharger upgrade!
