My plugs always looked like that on my 6. I gave up caring after awhile because there was nothing really wrong.


On a side note fuel injector cleaner is bad because it eats away at the solenoid and kills your injectors. That is bad.

What solenoid? And if cleaners are bad, why do they come in gasoline from the pumps?
The solenoids inside the fuel injectors. Fuel injector cleaner is very concentrated, and eats away at the coil inside the injectors. That's why people say don't use it. The stuff in gasoline is not as concentrated.
