(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. It is recommended you replace your ignition coils before tuning your n54, or every 35,000-40,000 miles thereafter.
Ignition coils are available in Bosch or Eldor. Eldor replaced Bosch as the OEM supplier of ignition coils in early 2016 – however the Bosch plugs are still a great replacement option. Given the price difference, we recommend the Bosch plugs unless you have experienced issues with them in the past.
