The spark plug forces electricity to arc across a gap. The electricity must be at very high voltage in order to travel across the gap and create a good spark. The spark plug needs to have an insulated passageway for this high voltage to travel down to the electrode, where it can jump the gap and be conducted into the engine block and grounded. The plug also has to withstand the extreme heat and pressure inside the cylinder. It must be designed so that deposits from fuel additives do not build up on the plug.

We can help with your car if you need a spark plug service

When you experience a sluggish engine, there’s a good chance that you could have a bad spark plug. Difficulty cranking, low momentum while running or sluggish performance in your engine can all mean spark plug failure. You can take your problem to a professional mechanic for a complete diagnosis, but there’s a way you can test the spark plugs yourself.
