Interesting, these sparkplugs claims up to 12% increase in HP
........................... There's been OTHER engines besides aircraft that use dual plug ignition, but that is not what we are talking about here. Here we are talking about "trick" nonsense
the Motown missle, circa 1973:

There's been stuff like fire trucks built long before I was ever born using dual plug/ dual ignition systems. These were not for horsepower, but reliability---and is the overwhelming reason on aircraft, NOT HP
IN FACT I remember reading about some of the teams running dual-plug hemi's that went back to single igniton--looked rather odd with the second plug hole plugged. At least one team found--don't remember which--that the HP gains were not worth the complications.
Here's a dual ignition on a 1918 Stutz, so nothing new here:
