How often should the spark plugs of a Vios be replaced?

[RyanRose]

The spark plugs of a Vios should be replaced approximately every 30,000 kilometers. Spark plugs are crucial components of a gasoline engine's ignition system, as they introduce high-voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. The Vios is a family-oriented entry-level model specifically designed and developed by Toyota for the Asian market. Based on the NBC platform, with an extended wheelbase, the Vios, developed on a small car platform, almost reaches the level of a compact sedan. In terms of appearance, the Vios does not have particularly distinctive features, but it presents an overall harmonious design with smooth lines, a cute front grille, and refined tail lights with fish-scale patterns.
