The Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. E3.10 is a 14mm, 0.375 reach plug with a gasket seat. It is used in multiple small engine applications, especially lawn & garden. The ground electrode is designed with E3s patented Diamond FIRE technology which is proven to improve power, increase fuel efficiency, and dramatically lower hydrocarbon emissions in long-term use. The unique ground electrode and full-size center electrode also provides optimal performance over an extended product life.

Product Features:

• E3's Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn.
• Quicker Starts - The patented edge to edge design concentrates spark energy resulting in easy starts in all conditions
• Energy - Increases both two and four cycle engine power up to 12% over conventional spark plugs
• Efficiency - Fuel consumption reduced up to 13% in small engines
• Emissions - E3's advanced spark technology produces cleaner burning combustion; toxic emission in long term use reduced up to 58%
• The Spark Plugs are pre-gapped at the factory to meet O.E. requirements
