E3 Spark Plugs E3.56 Automotive, Truck, Van and SUV OEM Replacement Spark Plug , Pack of 1
- 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 bet
