SETES BMW N54 to B58 Coil Conversion Kit

B58 Coilpack Ignition Upgrade for BMW N54 Engines

B58 Coils on N54? Yes sir. In N54 engines, misfires and unnecessary timing correction are often the first limitations encountered when increasing power. Upgrade your ignition system with the SETES B58 Coil Conversion Kit, engineered in Finland. This premium plug-and-play solution allows you to install high-performance OEM B58 ignition coils in your engine—no soldering, trimming, or permanent modifications required.

Why Upgrade?

• Helps eliminate ignition-related issues, such as persistent misfires in tuned engines
• Enables the use of latest-generation OEM B58 ignition coils for improved reliability
• Delivers a stronger, more stable spark—ideal for high-performance setups
• Reduces timing pull caused by weak or inconsistent ignition

What’s included in this kit:

CNC-machined billet aluminum brackets for precise, secure fitment (inc. 2x Torx screws)
Custom plug-and-play wiring harness compatible with factory connectors
Custom ignition coil boots

How to Upgrade?

No cutting, soldering, or wiring needed – this is a 100% plug-and-play upgrade. In addition to this kit, you’ll need a set of B58 coilpacks of your choice.
