I am not running E85, I know I would have to change spark plugs every 20k mile vs every 50k mile but I never heard anything about coils.
My old coils were still good but I got them changed any way just because of the miles on them. Plus, on FCP website they are dirt cheap.
Also, I am only getting misfires because of running higher boost. So, I wanted to see what plugs would be best choice or if I could still use OEM plugs with .018-.020 gap.
