spark plugs
Combustion chamber igniters
Spark plugs are devices that ignite the fuel-air mixture in internal combustion engines by producing an electrical spark.
Each cylinder in a gasoline engine requires its own spark plug, making them among the most frequently replaced engine components.
The term extends figuratively to describe someone who energizes or initiates action in a group: She was the spark plug of the whole operation.
Worn or fouled spark plugs cause misfiring, rough idling, and poor fuel economy.
