Spark Plugs

The spark plugs in your Mercedes' engine send electric current from its ignition system to the combustion chamber located inside the engine. The electric current sparks the fuel and air mixture which creates the combustion pressure that runs the pistons. Spark plugs also serve as exchangers of heat. They get rid of the thermal energy in the combustion chamber and convey heat to the cooling system. Healthy spark plugs are essential to a healthy engine. If your spark plugs are not working properly, your car might experience a rough idle generated by a misfiring cylinder, reduced fuel economy, difficulty starting the car or even a loss of power. The health of your engine highly depends on the condition of the spark plugs. Even a single dysfunctional spark plug in the engine will put additional wear and tear on the other plugs. Eventually, the bad plug can cause damage to other engine parts.
