I pulled the plugs out of my B18B1 and a couple had a whitish color to them. A coupe weeks ago I topped of the coolant reservoir and today it was a little low. Not sire how to post pics of the plugs, but I have one.

 

I'm assuming that you're asking what a normal plug is supposed to look like.

Google "How to read spark plugs". Pretty much what you need to do every time a question pops into your head.

 

White is better than black
