This Assembled By ECS ignition and pulley pack bundles two of the most popular R53 MINI Cooper S performance upgrades into one kit. It includes a reduced-diameter supercharger pulley for roughly a 15% boost increase, a tensioner stop, a performance coil pack with MSD racing red ignition wires, spark plugs, and an accessory belt, letting an installer address a full ignition service and a supercharger pulley swap in one afternoon.

Fitment: MINI Cooper S and John Cooper Works models, including the JCW GP and MC40, on the R52 and R53 chassis with the W11 1.6L supercharged engine.
