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 more compact than other offerings.
Connectors are removed in favor of directly splicing the wiring for the most compact solution.
This project has expanded to now include early N55, Later N55/S55, and the N20 kits!
Stock style terminals and gromets are also included just incase a customer wants to crimp them back on to return to a stock configuration in the future.
Please email me if there are any questions, Send Email.
