- Spark plugs screw into the top of an engine’s cylinders.
- It creates the electric spark required for ignition.
- A loose plug can cause rough running or abnormal noises.
A spark plug is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine.
A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto.
The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded.
