Order your spark plugs from Masterparts for the highest quality.

 

A spark plug is an electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed fuels by means of an electric spark that jumps the gap between electrodes.

 

Spark plugs have an insulated central electrode which is connected by a heavily insulated wire to an ignition coil or magneto circuit on the outside. Along with a grounded terminal on the base of the plug this forms a spark gap inside the cylinder.
