How often should the spark plugs be replaced in a Lavida?

[AdalynnMarie]

Lavida spark plugs should be replaced every 40,000 to 60,000 kilometers. The replacement procedure is as follows: Clean the dust and oil stains near the high-voltage terminal, then use a socket wrench to loosen the fixing screw of the high-voltage terminal. After removing the high-voltage terminal, use the socket wrench to loosen the spark plug. Next, insert the soft tube on the high-voltage terminal into the combustion chamber, pull out the old spark plug, insert the new spark plug, and secure it inside the high-voltage terminal where the internal clip fastens the spark plug. Important notes during replacement: After removing one spark plug, immediately install the new one, replacing them one by one rather than removing all at once before installation. When tightening the spark plugs, pay attention to the wrench position to avoid contact between non-rubber parts and the spark plug tail, which may cause insulation ceramic breakage.
