Spark plugs
Plug stuff...
Before I get jumped for not reading, I have perused the section in the sticky post  Just a quick question for confirmation or to be corrected. Here are 2 pics of my plugs 20k miles on them. Thanks Sox

Electrodes look nice and tan - you should be happy with those.

I would say that the discoloration on the ceramic is the gap that is not covered by the plug wire end.

It's called corona stain. It'll be okay.
