NGK IRIDIUM IX SPARK PLUGS are globally the best performance category of spark plugs having superior technology. These spark plugs use very precious Iridium metal at the tip of the center electrode of diameter 0.6mm and has a thermo-edge design for the central electrode maintaining a gap of 0.8mm. These features give anti-carbon fouling performance, smoothest running, and excellent acceleration with increased mileage and are used and appreciated by most racing bikes and cars all over the world.

NGK RESISTOR SPARK CAPS suppress electromagnetic interference generated by the engine's ignition system. NGK resistor covers feature a resistor element constructed of high-quality ceramic material, designed long enough to prevent interior flashover, and yet maintain constant resistance, with only slight variation under over-load conditions. The cover body is made of sturdy phenolic resin that endures high heat and high tension. The rugged special rubber liners on both ends prevent moisture from causing electrical leakage. Combined usage of the resistor covers and resistor spark plugs is more efficient to suppress ignition noise from engines in motorcycles, snowmobiles, farm tractors, and so on.

NGK RACING SPARK CABLES are flame retardant Ignition cables with Ultra-Low resistance and improve sparking energy leading towards engine performance levelled with a high degree of electro magnetic suppression. Durable in construction NGK Racing Cables feature high-temperature silicone outer jackets cotton braided, solid copper wire strand core.
