Firstly, prepare relevant spark plug replacement kit before replacing the spark plug. Secondly, open the hood, pick up the plastic cover of the engine, then remove the high-pressure pipeline, mark the position of each cylinder to avoid confusion, and use the spark plug sleeve to take out the spark plugs one by one. In the process of installing the spark plug, put the spark plug in the spark plug hole, then twist it a few times by hand, and then use the sleeve to tighten the spark plug to avoid damage to the spark plug. Next, install the high-voltage branch line in order, and then fasten the cover plate after the installation is completed.
