The multi-ground electrode plugs have been aroound since the 1930's in British racing aircraft engines ... what was developed for racing in the '30's was used in military aircraft in the '40's in a rather critical arena! In the 1950's some of that manufacturing capacity was used to capitalize on a growing USA market for cars and performance was a key issue. British-made multi-electrode plugs (with SIX ground electrodes) were sold by J.C. Whitney under the name 'Fire Injectors' ... for around $2.98 -- an astronomical price in 1957 dollars when regular spark plugs cost $0.49-$0.69, and had a lifetime guarantee! Does that gimmick sound a bit familiar to anyone??? I wonder if Split-Fire is a J.C. Whitney trademark?
