Somebody told me that there's only 3 HT leads on the FTO v6 engines -the other 3 plugs are powered through coilpacks - I was a aware of the coilpacks - but ehm - if one was to upgrade the HT leads - would new cables to the coilpacks not be an idea as well?
I know the gain is very small (if there is any) think of this more as a theoretical question.
