Stay away from E3 plugs

little back story, been running e3 spark plugs for about 10k miles, then one day out of no where CEL flashing, cylinder 1 misfire. Since i ran these plugs i also my idle has been rough. Anyways still looking into cause of this but the picture is interesting lol back to motorcraft plugs!
