E3 Spark Plugs E3.20 Small Engine and Lawn & Garden Spark Plug , Pack of 1

Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and limited warranty for the lifetime of the first engine the plug is installed in
DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
Significant potential power increase: > 6% to 12% (depending on engine class)
Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction

Product Description
The exceptional performance of the E3 spark plug starts with the unique open architecture of the E3 electrode. The design forces air gap discharges, creates the preferred edge-to-edge spark path, allows free replenishment of the spark zone with a fresh fuel/air charge, and exposes the flame front more directly to the piston head than other plug designs.Sparks naturally follow edge-paths as they leave an object. The E3 design presents multiple sharp edges to the center electrode. Sparks flow between these edges at lower voltages, facilitating easier discharge than standard designs. By forcing air sparks, the resistance to fouling is greatly increased in the E3 spark plug. This lowers the self-cleaning tempera… More >>
