A knuckle joint is used to connect two rods which are under the action of tensile loads. The distance between the tip of the spark plug and the central electrode is called the "spark plug gap" and is a key factor in the function of a spark plug. These are the best spark plugs available in the market. The spark plug works as a heat exchanger by pulling unwanted thermal energy from the combustion chamber and transferring heat to the engines cooling system. As a result, vehicles with such a system should have precious metals on both electrodes, not just on the central electrode, in order to increase service replacement intervals since they wear down the metal more quickly in both directions, not just one.[9]. In order to manufacture this part of the spark plug, a high-pressure, dry molding system is utilized.
