Firestone Spark Plugs with Packaging, circa 1942
01
Artifact Overview
Spark plugs ignite the air-fuel mixture in an internal combustion engine's cylinders. High voltage jumps across a gap between two electrodes on the plug's bottom and creates a spark. The plug's top is connected to a wire that runs to the distributor, which in turn is connected to the ignition coil and the battery.
