A spark plug is one of the components comprising the ignition system. It is typically situated at the top of the internal combustion cylinder. This component is responsible for conducting electric sparks that trigger the internal combustion engine with its efficient combustion operation. However, it needs to have precise timing and sufficient supply of electricity, so it needs to work with all the other components in a unified way. Sufficient supply of electricity will efficiently support the spark plug’s optimum performance, in which, perfect timing of the spark must be blown through the system. Imperfect timing may lead to spark plug’s misfiring. This event is the most effective factor that leads to spark plug’s deterioration.
