The advantages and theory of twin plugs and flame front travel vs igniton timing has all been said, but there's another VERY big advantage to it for a race car or aircraft.

Ignition systems all eventually fail and if you have twin ignition sytems and sparkplugs and one fails in service the plane won't crash and burn, and the race car will still finish the race.

Thats the biggest advantage for some folks.
