Modern Ignition Upgrade for BMW N55 and S55 Engines

Bring next-generation ignition performance to your BMW N55 or S55 engine with the SETES B58 Coil Conversion Kit. This premium plug-and-play solution replaces your factory coils with high-output OEM B58 ignition coils—the same coils found in BMW’s latest turbocharged engines.

Ideal for tuned builds and high-boost setups, this upgrade delivers a stronger, more consistent spark. The result is improved combustion, reduced misfires, and support for higher power levels with total confidence.

What's Included

  • CNC-machined billet aluminum brackets for precise, secure fitment
  • Custom plug-and-play wiring harness compatible with factory connectors
  • Custom ignition coil boots

Why Upgrade

  • Enables use of modern OEM B58 ignition coils for maximum reliability
  • Delivers a stronger, more stable spark—especially under boost
  • Helps eliminate ignition-related issues in tuned engines
  • No cutting or soldering – completely plug-and-play
  • Recommended setup: OEM B58 coils + NGK SILZKBR8D8S spark plugs (1-step colder)

Performance Refined. Reliability Delivered.
