Old plugs
Well this week I decided to replace my stock NGK PFR6T's with 1 step colder NGK BKR7E's sense I put on on my 2.85" pulley. Before the new plugs I felt a slight jumpyness around 3k rpms when I ease into the throttle. Well now that I have the new plugs in seem to be gone and could be mental but is seems to pull harder. Well here are some pics of the old plugs. I had a chart of what all the different shades meant but I can find it. Tell me what you guys think, good, bad, ugly, ok or whatever. Thanks
Here are some bigger pics of the same images for some close up viewing.

Do you run octane booster? They look like they have the same rusted orange coating as my plugs.
If not, those look like they were running pretty cold to begin with. Either you're running really rich or you don't rip on it much. Hard to really say unless you JUST made a pull before you took them out. They definately aren't lean looking so if anything you're erring the safe side.
