NGK 1-Step Colder Iridium Spark Plugs are engineered for high-performance engines equipped with forced induction or nitrous. The colder heat range helps control combustion temperatures, reducing pre-ignition and detonation often associated with boosted setups. A fine 0.6mm iridium electrode provides a precise, concentrated spark for efficient combustion, cleaner burn, and improved throttle response under load.Built with NGK’s high-strength copper core and alumina ceramic insulator, these plugs deliver excellent heat transfer, durability, and stability at high RPM. Trivalent plating protects against corrosion and thread seizure, while triple-seal construction prevents gas leakage. The extended-projection design enhances flame travel, making these plugs ideal for aggressive performance tuning and demanding driving environments.
