Spark Plug

Ceramic insulator body for spark plugs

Spark Plug

A spark plug, which carries electric current for igniting charge within the engine, has a metal threaded shell, electrically insulated from a central electrode by a ceramic insulator. The central electrode protrudes through the ceramic insulator into the combustion chamber.

The anti-abrasive, electrical resistance & temperature resistance properties of ceramic qualifies it for insulator material.
