The Plug for Serious Enthusiasts
Iridium has a very high melting point that's perfect for high-performance, high-tech engines. It is stronger than any other metal used in spark plugs.

  • Ultra-fine electrode (thin enough for spark consistency & accuracy, thick enough for max durability & longevity)
  • Reduces spark voltage requirement
  • Fuel efficiency & extreme ignitability
  • Improved throttle response
  • Outstanding acceleration
  • Superior antifouling, anticorrosion, and antiseizing properties
  • Quality NGK Spark Plugs
  • Sold individually
