[SanDelaney]

The method for removing spark plugs on a Sagitar is as follows: After opening the engine cover, unplug the electrical connector of the ignition coil, and also remove the circuit cover of the ignition wire harness. Use a specialized tool to pull out the ignition coil, then you can use a spark plug wrench to remove the spark plug. The structure of the spark plug is described below: 1. Steel Shell: The lower part of the steel shell has fine threads for installation into the cylinder head's spark plug hole. The upper part has an external hex nut for fitting a spark plug socket to tighten or loosen the spark plug. 2. The metal rod is the center electrode. The lower end of the metal rod contacts the upper end of the center electrode through a conductive glass body, and the upper end of the metal rod is equipped with a terminal nut. 3. Between the steel shell and the center electrode, there is a high-alumina ceramic insulator to ensure the center electrode remains insulated when electrified. 4. The lowest part of the steel shell is equipped with a curved side electrode. 5. The middle part of the steel shell's exterior has a copper gasket.
