Frequently Asked Questions
Convert your weak N54 factory coils to High Output B58 Coils!
To install B58 coils on N54 or N55 engines, we engineered billet aluminum adapter brackets. This comprehensive kit also includes plug-and-play connectors and boost for straightforward installation. This kit works with the BMS High Output B58 coils, Factory BMW B58 coils, and other aftermarket B58 coils.
Recommended Coils: (Sold separately) The BMS High Output B58 coils outperform the stock N54/N55 ignition coils by delivering 2-3 times more energy and a longer spark duration. These coil-on-plug units eliminate the need for spark plug wires and fit directly in the stock mounting locations.
