Faulty spark plugs will lead to misfire codes and therefore reduce your engine performance as your vehicle requires the spark to make power. Replace your faulty plugs today and restore those lost power on your BMW with the N55, S55 & S63 engine found on the M2, M2 Competition, M3, M4, M5 & M6.
Also fits F26 X4 M40iX (2014 - 2018)
We highly recommend replacing all 6 spark plugs at the same time.
