NGK race spark plugs Spark plugs used in racing are particularly high loads. At races, speeds over 15,000 rpm are often achieved. Temperatures, pressure and vibration in the combustion chamber are thus immense that conventional ground electrodes could cancel or melt. Therefore, race spark plugs often have specially developed ground electrodes, the most extreme shape is here the annular ground electrode. The spark jumps from the center electrode to the annular ground electrode.
