Can you run wasted spark with DFC (Direct Fire Coils)?
Do they produce a more powerful spark than the Zetec coils?
I have found these Toyota Denso coils are the right fit-
I would run them as 1 coil per cyl wasted spark can make them run hotter if they req long dwell times, I perfer the Chevy LS1 coils with leads.
