I do love them champions! Your plugs look like they came out of a 95 head and are doing Ok! Why did you change them? Make sure you get em gapped to match the dist the guy put in there. They look so good I would put em back. Those plugs should last 75/80K. Plug color went out pretty much with leaded gas.
