How many kilometers should the spark plugs of the Sagitar 1.4T be replaced?

[MacTravis]

The replacement interval for the spark plugs of the Sagitar 1.4T varies depending on the material: 1. Ordinary copper-core spark plugs should be replaced every 30,000 kilometers; 2. Precious metal spark plugs should be replaced every 60,000 to 90,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Taking the 2021 Sagitar as an example, its body dimensions are: length 4753mm, width 1800mm, height 1462mm, wheelbase 2731mm, and fuel tank capacity 50 liters.
