OEM BMW S55 Ignition Coils
These OEM ignition coils are direct replacements for the F80 M3 and F82/83 M4. Ignition coils are the key to efficiency and performance for your BMW. While newer ignition coils will not generate additional horsepower, they will improve your cars performance by unleashing lost horsepower caused by faulty or old ignition coils.
- Improves acceleration if your S55 is experiencing sluggish acceleration
- Fixes long starts and cold-starting issues
- Prevents misfires and pre-detonation
- Smoothes engine performance and rough idling
All ignition coils are sold with the boot and connector. A bad coil may cause a fault code but will not always cause a check engine light. You can test ignition coils by moving them around the different cylinder banks to see if the misfire code will follow to the new bank. These ignition coils are additionally the OEM plugs for the N55 engine as well.
*Unless you have a strong preference on using OEM products, we recommend the Bosch ignition coils as they are $110 cheaper and we have not noticed a decrease in lifespan or performance compared to the Delphi brand.
