Can Spark Plugs Be Used After Cleaning?

[StJameson]

Cleaned spark plugs can continue to be used if they exhibit minimal wear. Generally, spark plugs should be replaced after driving 40,000 to 60,000 kilometers under normal maintenance conditions, but this may vary depending on the brand and engine type. It is recommended to follow the vehicle's manual for specific guidance. Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs between 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the engine hood and remove the plastic engine cover. Detach the high-voltage ignition wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove each spark plug one by one. During removal, check for any external debris such as leaves or dust, and ensure the area is thoroughly cleaned. Insert the new spark plug into the spark plug hole, hand-tightening it a few turns before using the socket wrench to secure it. Reinstall the high-voltage ignition wires in the correct firing order, then reattach the cover.
