What Is A Spark Plug And Why Is It Important?
A spark plug is a small cylindrical-shaped part that serves two important purposes:
- Produce enough spark to ignite the air/fuel mixture
- Spark the air/fuel mixture up to 3,000 times per minute to keep the engine running smoothly
The spark plug is screwed into the cylinder head. The top end of the plug is connected to the ignition coil, from which it draws a high voltage electric current. The bottom end has a ground electrode that helps create enough spark to ignite the air/fuel mixture.
