How often should the spark plugs on an Excelle be replaced?

[SanJoseph]

The spark plugs on an Excelle should be replaced every 3 years or 60,000 kilometers. Under normal maintenance conditions, car spark plugs should be replaced after 40,000 to 60,000 kilometers of driving. However, this may vary depending on the brand and engine, so it is recommended to follow the owner's manual. You can refer to the following standards for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust, and make sure to clean it 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 according to the firing order, and then snap the cover back into place.
