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
