How often should the spark plugs be replaced in the SAIC Volkswagen Lavida XR?

[ElenaMarie]

Under normal maintenance conditions, the spark plugs in the SAIC Volkswagen Lavida XR should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to refer to the owner's manual for specific guidance. You can follow these general standards for maintenance and 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 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood and remove the plastic engine cover. Then, disconnect 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. While removing them, check for any external debris like leaves or dust and ensure the area is clean. Insert the new spark plugs into the spark plug holes, hand-tightening them first before using the socket wrench to secure them. Reinstall the high-voltage ignition wires in the correct firing order, then reattach the engine cover.
