The NGK Iridium IX spark plug four-pack targets performance enthusiasts seeking sharper throttle response and reliable ignitability. A fine iridium tip delivers durable, consistent sparks while the tapered ground electrode improves starts, idle and throttle response. Trivalent metal plating offers corrosion and seizing protection, and the insulator and copper core support heat removal for stable operation in modified or higher-performance scenarios.
