Spark plugs
Consist of a central insulated electrode and contact connected to the body. The body has threads at the base for installation in the cylinder head; on top of the central electrode there is a terminal for connecting to a power source. When high voltage is applied to the central electrode, a spark occurs between the electrode and the contact or contacts, which ignites the fuel mixture in the cylinder.
