Plugs And Coil Question

Autolite HT0, its one step colder for spark plugs as for coils stay stock no need with mild or even moderate mods

I have around 90,000 miles on my Champion 7989 one piece spark plugs. They have been great. I pulled them and checked them when they had 60,000 on them. I'll soon replace them with the same thing and not worry about them coming apart like the Autolites can. You shouldn't need a colder plug unless you are using nitrous or boost. I agree with stock coils, no need to replace them if you aren't having problems.
