The B58's require some wiring changes and brackets to mount them....seems like a royal pain in the butt.

That being said...I'm running the OEM Delphi coils from FCP Euro and I should be making close to 565-575hp at the tires on an E40 mix and bigger turbos at 27psi....and I have no issues with misfires.

With 100k miles on your coils......ANY new coils are going to help big time!!

If I were you...I would just order the N55 eldors from FCP with the lifetime warranty and be done with it 👍
Thanks for the reply, are N55 eldors different than N54 eldors? I thought the two shared coils.
