Replacement ignition coils. Your car's ignition coil(s) is just as important as your spark plugs. Problems with a coil can range from a simple misfire to a no-start condition on the engine so it's important to maintain the coils just as you would any other ignition component.
Starting with the M50 engines in 1991, BMW's igntion systems use an individual coil for each cylinder (coil-on-plug ignition). While the improved performance and smoothness is without question, these coils have a shorter lifespan than the older single-coil designs.
