 Why Upgrade to B58 Coils on an N54?

•  More Reliable & Consistent Spark Output – Supports higher horsepower builds

•  Essential for High-Boost Applications – Reduces ignition-related misfires

•  Longer Lifespan than N54 Coils – B58 coils are newer, more durable, and handle high stress better

•  Better Combustion Efficiency – Results in smoother power delivery and improved throttle response

The stock N54 ignition coils degrade over time, leading to misfires, power loss, and weak ignition under high boost. Upgrading to B58 coils with this adapter kit ensures better spark energy, stronger performance, and improved reliability—making it the go-to ignition upgrade for modified N54 builds.

 Recommended Supporting Mods for Maximum Performance:

 B58 Ignition Coils (Sold Separately – Available on Our Store)

 Upgraded Spark Plugs (One-Step Colder for Tuned N54s)

 Custom ECU Tune to Optimize Ignition Timing

 Methanol or E85 Tuning for Additional Power Gains

 No additional coding required. Works seamlessly with stock & tuned ECUs.
