Faulty ignition coils will lead to misfire codes and therefore reduce your engine performance as your vehicle requires the spark to make power. Replace your faulty coils today and restore the lost power in your BMW/Mini N13, N14, N16, N18, N20, N26, N45, N46, N51, N52, N55, N62, N73, N74, M54 and S55 engines!
We highly recommend replacing all 6 coils at the same time.
