It splits the spark to prolong the spark plug’s life, reduce fuel consumption and help the engine run a bit cleaner and cooler. It seems to work fine but definitely has a different sound when cranking the motor.

It’s a spark plug. I do not have any means to compare output, other than the mower starts and runs.

Stubby74. I purchased a spark plug without having a reference card that is usually found next to the parts guide. Unfortunately, I purchased the wrong plug and can’t return it. I would recommend that customers research before going to HD.
