Spark plugs used for racing must withstand especially hard stresses. The speeds during a race are frequently in excess of 15,000 rpm. Temperature, pressure, and vibrations in the combustion chamber are so immense that conventional ground electrodes could break or melt. For this reason, racing spark plugs often come with specially designed ground electrodes, the most extreme form with a ring-shaped ground electrode. The spark jumps from the middle electrode to the ring-shaped ground electrode.
