For those of you running B58 coils, are they worth it? Do you have to modify them past the point of return and cannot warranty them should something go wrong? Have you noticed smoother operation at low load compared to Eldors?

I am hesitant about the B58 coils because of the cost of the adapter plate, modifying the factory VC, modifying coils, etc. If Eldor N54 coils can support 600 crank horsepower without hiccups I think that's the route I'll take.

Thanks
I'd agree totally with iqraceworks, just go with the Eldors from FCP. Those Dinan ones posted in the other thread also seem fine. As stated at 100k your coils are probably toast.

No need to mess around with brackets, wiring etc.
