A spark plug (also known as an ignition plug) is an electrical device that converts electrical energy to mechanical energy, which then causes combustion in the engine to create heat, pressure and power.

How often to replace your spark plugs

In most cases, spark plugs should be replaced every 100,000 miles or two years. The only way to know for sure when they need to be replaced is by checking the gap between the electrodes on the old one. If it’s bigger than 0.024 inches, you need a new one.
