IMHO those plugs look just about perfect. I think the discoloration around the ceramic is from the imperfect seal between the porcelain and the metallic part of the plug. Nothing to worry about IMO.
Yeah, I totally agree. I'm really impressed that an engine with 85,000 miles on it is burning so clean.IMHO those plugs look just about perfect.

I watched some youtube videos where Denso Plugs had loose tops when pulled.I did not know that. Thanks for sharing this with me.
That's not from an oil leak, is it?Thought you guys might like to see a 'bad' plug from my V-6 Accord.

To say I'm disappointed in finding this is an understatement.
The ceramic insulator in the center of 20CRVEX13's plug is cracked. The other deposits could be from burning a little oil. The brown ring on your plugs is 100% normal.Is that carbon build up? What does that mean?
Those look clean for 85k. Top tier fuels really do make a difference!Yeah, I totally agree. I'm really impressed that an engine with 85,000 miles on it is burning so clean.I change my oil regularly and rarely burn anything other than Shell gas. I wonder if that makes a difference.
