Oliver Lodge invented the electric spark ignition (the Lodge Igniter) for the internal combustion engine. Two of his sons developed his ideas and founded the Lodge Plug Company. Oliver Lodge is better known for his pioneering work in radio and was the first man to transmit a message by wireless.
During the early 1900s, France was the dominant manufacturer of spark plugs. Frenchman, Albert Champion was a bicycle and motorcycle racer who immigrated to the United States in 1889 to race. As a sideline, Champion manufactured and sold spark plugs to support himself. In 1904, Champion moved to Flint, Michigan where he started the Champion Ignition Company for the manufacturing of spark plugs. He later lost control of his company and in 1908 started the AC Spark Plug Company.
I have an old Lodge plug here.New in the box. Was for an Alfa Romeo actually has 4 electrodes on it. Sort of resembles the old JC Whitney "Fire Injector" plugs.
Brisk brand looks similar.
VTAG & Torque Master plugs use a circular electrode.
I've seen them demonstrated on simulators and the perform best when there is a superimposed high frequency on the high voltage. Kind of like the HF start on a Tig/HeliArc welder
