    2012 CR-V Spark Plugs?

    I just changed the spark plugs in my 2012 CR-V, which has close to 85,000 miles on it, with a new set of NGK's. The old spark plugs look to be in relatively good condition, except for the area around the ceramic part of the pkug. Please see the attached images.

    Is the discoloration due to water intrusion or something else?

    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. I change my oil regularly and rarely burn anything other than Shell gas. I wonder if that makes a difference.

    They look a lot like the plugs that came out of my '02 V-6 after 100k miles when I had them changed at the 105k check up.
    I wish my current '11 V-6 plugs looked that good, but, with the VCM system they don't.
    I use and have been using Chevron gas for years now. I'm sure sticking with one brand helps and the oil changes don't hurt either. I hope our CR-V's plugs look that good when it comes time to change them. At the rate we drive that should be in another 5 yrs.

    Do not confuse the normal corona stain trace with a soot traces of gases breakthrough.

    I watched some youtube videos where Denso Plugs had loose tops when pulled.
    The only plug I'll put in my car is an NGK.

    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.

    Is that carbon build up? What does that mean?

    I just pulled the plugs in my 06, 2.4 @180,000 miles.
    They looked perfect--The plugs have 30K on them.
    Only NGK for me.
