The condition of spark plugs can provide some insights into the overall condition of an engine, but it is not a definitive indicator. Spark plugs can offer clues about combustion efficiency, fuel mixture, and general engine health. However, they should not be solely relied upon to assess the engine's condition.
In your case, the Champion 12ZR-6SPP2-1 spark plugs were fitted by the dealer in September 2017 when your Mini had 19,602 miles on the odometer. Given that you have driven an additional 20,844 miles since then, it is reasonable to assume that the plugs have experienced wear and deposits over that period.
During a routine service, the spark plugs should have been inspected by the technician. They would have checked for any signs of fouling, such as excessive carbon deposits, oil residue, or unusual wear. If the plugs were in poor condition, it could indicate issues with combustion or other engine problems.
However, without further information about the condition of the spark plugs after the recent service, it is difficult to make an accurate assessment. It's best to consult with your mechanic or service technician who performed the service. They will have firsthand knowledge of the condition of the plugs and can provide a more informed opinion about the overall health of your engine.
