E3 Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new E3 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.

Product Features:
  • E3's DiamondFire edge to edge 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%
  • E3 Spark Plugs are pre-gapped at the factory to meet O.E. requirements
  • E3 PowerSport spark plugs properly installed in non-commercial equipment, are warranted to properly discharge a spark, and to be free of defects in material or workmanship. Spark plugs damaged by abuse, accidents, or improper installation or applications are not warranted

    Comments about E3 Premium DiamondFIRE Electrode Power sport Spark Plug:

    I use E3 plugs in 3 of the 4 racing lawn mowers we run. The forth mower requires a size plug that has no E3 conversion yet. These plugs help the engines start faster and idle stronger with less stalling. That means less wear and tear on the batteries and starters.

    • Q:

      my bike is a 2004 kawasaki kx100. on the E3 website, my spark plug number is referenced to E3.31. would the E3.32 be too hot of a plug to put into the kx100?
