Open wire feedlines used to have "spark balls" for lightning protection
on high power transmitter installations. Admittedly, the transmitters
used tubes.

That is at the pressure inside the combustion chamber. At atmospheric
pressure, they fire at much lower voltages; however, Walter's point is still
valid. Turn on voltage is far more reliable with gas discharge tubes.
Sparkplugs were probably more helpful with tube gear than with today's solid
state gear.
