Essentially, spark plugs are the pulse of your engine. It forces electricity to arc across a gap and the electricity must be at a very high voltage. As the piston travels up the first time, compressing the air-fuel mixture inside the combustion chamber, the distributor sends an energy surge along the spark plug wire.
