The spark plug is essentially the first step in your engine’s combustion process. It forces electricity to arc across a gap, just like a bolt of lightning. The electricity must be powerful in order for it to cross the gap and create a quality spark. While it might seem like a small part, it needs to be able to withstand the extreme heat and pressure inside the cylinder, so they need replaced during regular service.
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. When the surge reaches the spark plug, it fires, which ignites the air-fuel mixture. This explosion inside the combustion chamber forces the piston down again.
When your spark plugs are worn out, you will notice a decrease in power and efficiency, so be sure to replace them as soon as possible to restore your vehicle’s performance.
