BMW N20/N54/N55/S55 B58 coil conversion Products.
 


This page is dedicated to B58 coil conversions for N20/N54/N55/S55 Engines.
Originally I designed my own conversion for my 2008 335i N54 based on wanting a more modular design that is cheaper and removes conversion connectors in favor of directly splicing the wiring for the most compact solution. This has now grown based on requests for a kit for the early N55, Later N55/S55 and the N20.
