What is the replacement interval for spark plugs in the Hyundai Elantra?

[LeJulia]

The Elantra requires spark plug replacement every 60,000 to 80,000 kilometers. Under normal maintenance conditions, automotive spark plugs should be replaced after 40,000 to 60,000 kilometers of driving. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. You can refer to the following maintenance standards for replacement: platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000-80,000 kilometers. Spark plug replacement procedure: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. During removal, check for external debris like leaves or dust and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it for several turns before using the socket wrench. Reinstall the high-voltage distributor wires according to the firing order, then secure the cover plate.
