Review on ACDelco 9628E Professional Spark Plug by Anthony Epps

I accidentally tore the outer insulation on one of these wires when trying to get at the contact that snaps onto the spark plug. Took advice from a YouTuber he shouldn't have. After getting everything right (silicone lube and patience) I was able to verify that the terminal is 10x larger than this 454. Yes, it actually clamps and makes a good connection (who would have thought). Luckily when I ripped the outer insulation it didn't damage the fiberglass so I was able to hit it with heat shrink tubing (shouldn't spark at this point as the spark plug is still the path of least resistance. I think I'll find it install next.
