Help reading plugs

[natethegreat]

Hey all, Just pulled a couple of plugs to see which ones i bought, and while doing so thought they looked kind of lean. I'm running a topswap on the stock pulley, and when i had it tuned he said it was tuned a little rich. Because of that i think it has fouled my 02. Also, my charger started to make noise, so my i just took the belt off for the time being until i could find another supercharger. It was stumbling for like half a second, but it does it with our without the belt. Anywho, here is the picture. I pulled two, and they both looked like that. Copper AL 103's.

Nah, thats still rich and too cold of plug.

If you were lean the tip would be browner and the white with the electrode would not be black/brown near the top. It would be all white and almost like a chalk white coving it.

Replaced all the plugs, so i figured id show you the rest.

This is the rear bank, #6 is on the right, and smells like oil, but doesn't really look oil fouled. I don't think its a huge problem.

And heres the front bank
