Spark plugs play a vital part in the overall engine operation. A spark plug provides ignition to ignite the fuel and air mixture. The correct spark plug and heat range allow precise engine performance. The operating temperature range is between 932 to 1472 degrees for spark plugs. In order to be self-cleaning, a minimum range for a spark plug should be 842 degrees. By design, the heat range of a spark plug is determined by the length of the porcelain insulator. Too low of operating temperature will cause carbon fouling, and concurrently too hot could eventually cause engine damage. It is always the best rule to read and understand your owner’s manual for the proper spark plug for the engine.
