Developed in collaboration between Trust / GReddy and NGK Japan, the GReddy Iridium Tune Spark Plug offers the perfect balance of racing performance and reliability. Engineered for high-performance and tuned engines, this plug features a 0.6mm ultra-fine iridium alloy center electrode that provides powerful and consistent ignition, even under extreme conditions.

The iridium alloy’s high melting point ensures exceptional durability and stable spark strength at both low and high voltages, improving throttle response, combustion efficiency, and overall power delivery. The outer electrode is nickel-based with a projecting design for optimized flame kernel growth.

Ideal for naturally aspirated and turbocharged Japanese engines, this plug enhances mid- to low-end torque while maintaining strong ignition stability at high RPM. It is recommended for drivers seeking improved performance, reliability, and resistance to knocking in both street and circuit applications.

JIS and ISO types are available in heat ranges 7 and 8, L type in heat range 8, and B type in heat range 8.
