What material is the original spark plug of the Sylphy Classic?

[OEllie]

The original spark plug of the Sylphy Classic is an NGK platinum spark plug with a lifespan of approximately 40,000 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 user manual. The following standards can be referenced 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 engine hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. 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 external debris such as leaves or dust and ensure they are thoroughly cleaned. 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 secure the cover.
