NGK Iridium IX Spark Plug - R0451B-8

The NGK Iridium IX Spark Plug is a high-performance ignition component designed for demanding engine applications. Featuring a 0.6 mm iridium center electrode tip, it offers superior ignitability while maintaining durability. The spark plug also incorporates a tapered ground electrode that promotes enhanced flame kernel expansion for improved combustion efficiency. Its heat range is specifically designed for high-performance environments.

This spark plug is engineered to deliver outstanding acceleration, high fuel efficiency, and a long service life, making it an ideal choice for engines that require maximum performance. It is designed to provide a stronger spark from your existing ignition system. The recessed fine wire iridium center electrode reduces voltage requirements, allowing for a stronger spark that ignites the air-fuel mixture more effectively. The nickel ground electrode minimizes quenching for better combustion. This plug is handcrafted in Japan to withstand extreme racing conditions.
