Why do we need spark plug in petrol engine?
Spark plugs provide the electricity necessary for combustion to happen by igniting atomized fuel in an engine’s cylinders. However, they need a constant supply of electricity to do that. This is the job of your spark plug wires. And, just like your plugs, the wires wear out over time.
