NGK is now the specialist and world leader in ignition and sensors. Globally recognised for its expertise and know-how in technological innovation, NGK Niterra has become over the years the benchmark for manufacturers, distributors, and repairers in the automotive, two-wheeler, garden machinery, and marine sectors. Ensuring the connection between the coil and the spark plug, the harness is one of the essential components of the ignition system for petrol engines. Thanks to its expertise and know-how, Niterra provides cables and harnesses that perfectly complement its wide range of spark plugs and ignition coils. Racing spark plugs Spark plugs used in racing must withstand particularly high voltages. Engine speeds reached during a race often exceed 15,000 rpm. The temperature, pressure, and vibrations in the combustion chamber are so significant that conventional ground electrodes could break or melt. That’s why racing spark plugs are often equipped with ground electrodes specially designed for competition, with the most extreme design featuring a ring ground electrode. The spark "jumps" from the central electrode to the ring ground electrode.
