Default Vintage Spark Plugs

I have some vintage spark plugs. I did some digging to find out what I have. The AC in AC Spark plugs is the intials for Albert Champion the same Champion as the spark plugs. I have spark plugs that were made for a L88 and a Ford 427 FE. The FE spark plugs would have not been original equipment even though GM made a set to fit. The spark plugs were made in Flint Mich. The L88 plugs fit into a Pontiac head, I have not tried them to see how they work. The lettering on the plugs in not the common green color of the other AC spark plugs.

Cool
Oliver Lodge
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.

Albert Champion
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
