These coils have a lot more spark energy. The larger the coil, the more energy it can provide. Also, being out in the open, they will not overheat and create misfires like coils that go into the factory spark plug tube.

The standard coils 105 millijoules at 12volts

The H.O. (high output) coils deliver 210 millijoules at 12volts
