spark plug
Engine's ignition device
A spark plug is a device that produces an electric spark to ignite fuel in an internal combustion engine.
Each cylinder has one, and worn spark plugs cause misfires and poor performance.
Figuratively, a spark plug is someone who energizes a group or drives activity forward: She's the spark plug of the whole operation.
