Can Spark Plugs Be Reused After Cleaning?

[Ulysses]

Spark plugs can continue to be used after cleaning if the wear is minimal. Generally, they should be replaced after driving 40,000 to 60,000 kilometers under normal maintenance conditions. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. Platinum spark plugs should be replaced at 40,000 kilometers, standard 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 engine's plastic cover, and remove the high-voltage ignition wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. Check for any external debris like leaves or dust and 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 high-voltage ignition wires in the firing order and secure the cover.
