How often should the spark plugs of Geely Emgrand be replaced?

[DelEthan]

Geely Emgrand spark plugs should be replaced every 3 years. The original equipment uses nickel alloy spark plugs, and double iridium spark plugs can be used as replacements. Spark plugs are a crucial component of the gasoline engine ignition system, responsible for introducing high voltage into the combustion chamber and generating sparks by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Geely Emgrand is a sub-brand under the parent brand Geely. Taking the 2019 Emgrand as an example, the car's body dimensions are 4632mm in length, 1789mm in width, 1470mm in height, with a wheelbase of 2650mm, positioning it as a compact car.
