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?
