That's a real mystery. No idea. I gapped them and then verified the gap on all 8 before install. For the record, my experience is that most plugs have some gap out of the box too. Therefore, I was either sleepwalking one night and closed the gap or something weird happened. Attached are photos. The color difference must be from lack of combustion / proper ignition???
