Convert your weak N54 factory coils to High Output B58 Coils!

To install B58 coils on N54 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 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.
