Manufacturers and suppliers Industrial Spark Plugs Gap Grounded Ignition Electrodes for oil burner, furnace, oven and also known as VD Plugs.
The purpose of a spark plug is to provide a place for an electric spark that is hot enough to ignite the air/fuel mixture inside the combustion chamber of an internal combustion engine. This is done by a high voltage current arcing across a gap on the spark plug.
Adjusting the distance between the two electrodes is called gapping your spark plugs.
