E3 Lawn & Garden Spark Plugs have a patented Edge-to-Edge DiamondFire ground electrode that has been proven to burn the fuel more efficiently, providing more power and using less gas. The design and more complete burn also dramatically extends the useful life of E3 Diamond Fire plugs. In addition to more power and better fuel efficiency, the complete burn of E3 plugs produces radically fewer emissions.
The E3 Small-Engine Spark Plug replaces a wide variety of spark plugs used in small 4-cycle engines.

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.

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.
