Spark Plugs

Spark Plugs

When you go to start your car the spark plugs are right up there at the list of the most important components in the process. Spark plugs deliver an electrical current to the combustion chamber inside the engine, that in turn ignites the fuel and, as a result, starts the engine. Spark plug gaps, as they are called, are a hook-shaped piece of metal at the top of the plug that affects whether or not the spark is transferred. A gap that is too wide can mean that the current cannot 'jump' and implies that the spark plug in question has worn and needs changing.
