What is the lifespan of spark plugs in Lavida cars?

[NathanRose]

Lavida spark plugs have a service life of 60,000 kilometers. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe them. The condition of the spark plugs can be judged based on their appearance and color. Normal spark plugs have insulator skirts and electrodes that appear gray-white, gray-yellow, or light brown. Properly functioning spark plugs have insulator skirts that are reddish-brown, with electrode gaps between 0.8-0.9mm and no signs of electrode burning. If the spark plugs are contaminated with oil or deposits but are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong heat range was selected or that the air-fuel mixture is too rich, with oil seeping up.
