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 Lawn & Garden spark plugs are warranted against wear, defects in materials and workmanship for a limited lifetime.
