How Often Should Crown Spark Plugs Be Replaced?

[McAnastasia]

Crown spark plugs use iridium spark plugs, and it is recommended to replace them after driving 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for leaves, dust, etc., on the outside and make sure to clean them thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires in the firing order, and then snap the cover back into place. Effects of damaged spark plugs: If the spark plugs are damaged, they can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The main problem, however, is difficulty in ignition, which affects the normal operation of the vehicle. Severe spark plug erosion, such as scarring at the top, broken or melted electrodes, or burn marks, indicates that the spark plug is damaged and should be replaced.
