The NGK Iridium IX spark plug is optimized for drivers seeking improved acceleration, fuel economy and ignitability. The fine iridium center electrode resists wear and maintains a consistent spark while the tapered-cut ground electrode enhances starting, idling and throttle response. Trivalent metal plating reduces corrosion and seizing, making these plugs a durable upgrade from standard nickel alloy spark plugs in higher-demand applications.
