Multiple sharp edges on center electrode: Provides more paths for the spark to follow, reducing electrode wear and extending plug life
Advanced E3 flame kernel shape: Promotes faster, more efficient combustion for increased power output
High nickel content alloy construction: Enhances durability and heat resistance for long-term use
Copper core with nickel alloy sheath: Improves heat dissipation to protect the electrode and maintain performance
Three supporting legs: Move heat away from the electrode, further reducing wear
Summarized by Shop
Race car drivers will tell you that the single sharp edge on spark plug electrodes wears out too fast for long term use. The E3 DiamondFire design presents multiple sharp edges to the circular sharp edge of the center electrode, which allows the spark to naturally seek the path of least resistance. The problem is that each time a spark ju
