NGK’s wide heat range is achieved with copper wire, providing superior heat dissipation compared to conventional iron cores.
Copper core ensures quick cooling of the electrode and insulator tip.
Raised pre-ignition rating with high-conduction copper and long-nose insulator.
Designed to meet the demands of high-performance engines.
Fine wire nickel center electrode requires less voltage for ionization, delivering a stronger spark for improved ignition and power.
Fine wire ground electrode reduces quenching, enhancing combustion efficiency.
Handcrafted in Japan to withstand extreme racing conditions.
Sold individually.
