Latest thoughts on best B58 coil packs and plugs for a modest tune?

[pbondar]

Got a misfire on cylinder 1..plugs and coils have been in for 15k-20k miles..

Running Nexsys B58 coil conversion with TTE500 turbos making 550 BHP on 21 psi boost on 99 Ron fuel

Latest votes on preferred coils and appropriate plugs to suit coils and tune ?…NGK plugs I assume..

Sadly in Europe that’s not an option..

Best B58 coils are Eldor, as far as i know, in europe you can only get them from BMW.

I’ve ordered Genuine BMW Ignition Coil pack 12138643360 B38 B48 B58

I have an early Nexsys kit…are there any issues with boots, springs etc?

Still need advice on plugs ?

Curious, but why did you go that route ?
Was there an issue with stock ignition system ?

I tend to over engineer / over think things..so when I decided to go hybrid turbos I did a stem to stern update..fresh index 12s, uprated LPFP. uprated LPFP controller, uprated inlets , bigger flow exhaust system, Wagner 3 FMIC , mr 5 inlet mod etc..so looked at uprated coil solutions..

So now ordered Eldor coils and NGK 1-Step Colder Spark Plug (97968)

I have noticed this. I would chime in and help but have zero issues on factory ign system and 2 step colder NGK.
Good luck though.
