The NGK Iridium IX spark plug is aimed at the performance enthusiast seeking improved acceleration, fuel efficiency and durability. It uses a fine iridium tip and tapered ground electrode for extreme ignitability, better starting and throttle response, with iridium alloy offering high melting point durability. Trivalent plating resists corrosion and seizing; these plugs suit modified or high-performance applications as an upgrade over OE nickel plugs.
