Iridium IX; Pre-Set Gap: 0.032"
The improved throttle response, superior anti-fouling and high-ignitability makes Iridium IX® ideal for the performance enthusiast. Iridium's extremely high melting point is perfectly suited to today's high-temperature engines, delivering outstanding acceleration, fuel efficiency and durability.

Features & Benefits:
  • Fine Iridium tip ensures high durability and a consistently stable spark
  • Iridium alloy has extremely high melting point, perfect for today’s high-tech, high-performance engines
  • Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties
  • Tapered ground electrode increases ignitability and minimizes quenching
  • High-grade alumina silicate ceramic creates a stronger insulator to reduce dielectric punch-through (caused by spark exiting through side of ceramic)
  • Cold-rolled threads prevent cross-threading and damage to cylinder heads
