How often should the spark plugs be replaced for the Verano 15s?

[DelSabrina]

The replacement interval for the Verano 15s spark plugs is between 40,000 to 60,000 kilometers. Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the owner's manual. You can refer to the following 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, remove the engine's plastic cover, and detach 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. While removing them, check for any external debris like leaves or dust and ensure everything is cleaned 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 correct firing order and secure the cover back in place.
