What in the hell would make these foul after 20 miles ??? More important, what would cause that huge gash on the number 3 plug ground electrode .... there is no way the ground electrode got smashed flat from me screwing it in . Number 3 looks like it never got spark because it's the only one without any carbon burn on it. They all had a burning ozone smell when I pulled them out of the hot engine block.
The old NKG plugs were completely brown on the spark tip but my engine was still running pretty good. I had to gap the new ones down pretty far to hit .31 !! The bolt size was also different 20mm for the old & 16 mm for the new ones (NGK V Power)
Any Ideas ??
