how dirty are my spark plugs?

They look a bit used lol. But thats typical on 100k mile plugs. I pulled mine out and they looked about the same but a bit whiter around the ceramic. But your engine should be fine...That chocolate color kinda is from seafoam as I recall because it changes the hue of the ceramic.
