E3 Spark Plug E3.40 Automotive Spark Plug, Pack of 1

Brand	E3 Spark Plugs
Model	E3.40

Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty

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

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 temperature of the spark plug, allowing colder heat ranges to be used if desired.E3's distinctive spark plug design has proven, in testing in a range of engines, to simultaneously increase engine power output, reduce gasoline consumption, decrease hydrocarbon and carbon monoxide emissions from the engine and materially extend the life of the spark plug.
