NGK’s wide heat range achieved using copper wire instead of conventional iron cores for superior heat dissipation.
Copper core dissipates heat quickly, cooling the electrode and insulator tip.
Raised pre-ignition rating with high-conduction copper and long-nose insulator for enhanced performance.
Designed specifically for high-performance engines, ensuring reliable ignition under extreme conditions.
