Why Upgrade to Smart Coils for Your N54 Engine?

The factory "dumb coils" lack built-in ignitors, relying on signals from the DME. This can lead to MOSFET transistor failures and costly repairs. Our kit uses smart coils to reduce strain on the DME and provide better spark performance. Learn more here.

Why Choose Our Ignition Upgrade Kit?

Our kit ensures superior performance while minimizing stress on the DME, unlike other high-dwell coil upgrades. Trusted by track winners and drag record holders for reliable power delivery.
