NGK RACING PLUG R6918B-8 4492 NG4492

NGK RACING PLUG R6918B-8 4492 NG4492. NGK’s wide heat range is achieved with copper wire for superior heat dissipation and performance. Copper core ensures rapid cooling of the electrode and insulator tip. Raised pre-ignition rating with high-conduction copper and long-nose insulator. Fine wire platinum center electrode requires less voltage to ionize the gap, delivering a stronger spark for improved combustion. Platinum-tipped center electrode offers enhanced durability and long-lasting performance. Fine wire nickel alloy ground electrode minimizes quenching, promoting better ignition efficiency. Specifically designed for high-performance engines in demanding environments. Handcrafted in Japan for durability in extreme conditions. Sold individually. Part Number: 37-R6918B-8.
