Spark Plugs

Spark plugs carry a high voltage into the engine's combustion chamber and convert it into a spark, igniting the air/fuel mixture. This generates the power that keeps the engine running. Even at idle, each spark plug fires 375 times per minute.

Over time, the spark plug's tip (electrode) wears out.

The outer shell (insulation) may even crack or separate allowing the voltage to exit the plug where it is not intended.
Misfire results, which causes the engine to run rough and lowers fuel economy.
