spark plugs
I know this is an old discussion, I've look at the old thread but I was hoping to find something new regarding using E3 plugs. I have a W351 stroked putting out 470HP. I am using Autolite plugs now, but was thinking when I changed them, going to E3's. Do I need to gap them, or use them straight out of the box? I understand they burn cleaner than Autolite. Any help appreciated
