Replacing the spark plugs on your BMW E46 is recommended routine maintenance. BMW recommends replacing the spark plugs on E46 models every 100,000 miles and every 60,000 miles on M3 E46 models. With all the major engine design changes over the years, spark plugs now last up to three times as long as they did in years past. This is good and bad. It means you save money and time not having to service them so frequently, but run the risk of a spark plug seizing in the cylinder head.
I suggest replacing your spark plugs every three years regardless of mileage. If the last time they were serviced is unknown, replace them right away. If possible include pictures of these as well. I do not have stock photos of faulty spark plugs but I can add a description of failure modes. I did so below, right after the spark plus is removed.
