The NGK Iridium IX spark plug pack of four is built for enthusiasts seeking improved acceleration, fuel efficiency and durability. Its fine iridium center tip and tapered ground electrode increase ignitability and throttle response while resisting fouling. Trivalent metal plating reduces corrosion and seizing, and robust insulator and copper-core construction aid heat removal for consistent spark performance in modified or high-demand applications.
