Google ...park plug chart ..
In my case no chart needed lots of corrosion ....
Corrosion ? I assume you are speaking of that greenish crap found on metal when exposed to water and air.
What, do you live and live at the bottom of some seashore?;)
Seriously, please describe what you see around the spark plug electrode, I'd like to know what corrosion looks like. I may be needing an update on the colors of corrosive spark plugs...
