I'm no expert, but it looks normal for a plug that was misfiring
. What was the cause of the misfire? I'd assume a faulty spark due to either the coil and/or the plug. Maybe dielectric grease around the insulators would help mitigate any weak spark? Maybe sparks weren't torqued or gapped to spec? Maybe the new spark plugs were just bad to begin with? NEW stands for Never Ever Worked
