NGK SPARK PLUG BKR7EIX-11 NG6988

NGK SPARK PLUG BKR7EIX-11 NG6988. Iridium IX Plug, 14mm Thread Size, 19mm (3/4) Reach, 5/8 (16mm) Hex Size, Gasket Seat, Resistor, Solid Terminal Nut, ISO Length, Projected Tip, Fine Wire (0.6mm) Iridium Center Electrode, Tapered Cut Ground Electrode, .043 (1.1mm) Gap, Heat Range 5. NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to design an ultra-fine (0.6mm) center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability. The combination of fine wire center electrode, tapered cut ground electrode, corrugated ribs to prevent flashover, pure alumina silicate ceramic insulator providing superior strength and better heat transfer, copper core to aid in heat removal, and triple seals to prevent leakage contribute to improved performance, acceleration, and fuel efficiency.
