UPPER BUSHING SERVICE SET

Ignition coils are crucial for the performance and efficiency of M42, M50, S50, and M60 BMW engines. Each cylinder has its own coil for optimal efficiency and precise firing, ensuring complete fuel/air mixture combustion. A faulty coil leads to misfires, rough running, poor fuel economy, and potential damage to catalytic converters and O2 sensors. While faulty coils can often be isolated, replacing coils in complete sets is recommended to prevent damage from voltage spikes. Price is per coil and includes the rubber connector boot (remove for M42 engines). This coil is produced by Bosch, an original BMW supplier, and comes with a two-year warranty.
