How many kilometers should the spark plugs of Volvo XC60 be replaced?

[LaHarley]

Under normal circumstances, the spark plugs of Volvo XC60 should be replaced every 40,000 kilometers, but the actual usage conditions should also be taken into consideration. Spark plugs are crucial components of the gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber and generate sparks by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. In terms of exterior design, the 'Volvo' lettering on the tailgate of the XC60 features a more spaced and bold font. To further emphasize the sporty characteristics of the XC60, the sill plates are equipped with anti-scratch strips and integrated front and rear skid plates that blend seamlessly with the bumpers. For the interior, the new Volvo XC60 does not adopt the concept version's design but instead uses the more mature center console design style of the Volvo S80. The layout of the function keys in the T-shaped control area, the floating center console, and the gear arrangement are very similar to those of the S80. However, the multimedia display above the central air conditioning and the wood grain center console trim remain distinctive features of the XC60.
