(6) OEM BMW N54 Ignition Coils – With Spark Plug Connectors
Old ignition coils may cause misdires, rough idling, stumbling, poor fuel economy, and overall poor performance. We recommend replacing the BMW S54 ignition coils every 70,000-80,000 miles. Ignition coils are available in Bosch or Eldor. Eldor replaced Bosch as the OEM supplier of ignition coils in early 2016, making them both OEM products.
We recommend Bosch as they are a bit cheaper and a high quality product that original equipment on the S54 engine.
