Automotive spark plug is an essential component of a vehicle meant for delivering electric current from the ignition system to the combustion chamber in the engine. Spark plug ignites the mixture of air and fuel inside the combustion chamber with an electric spark when the pressure within the chamber is at an optimal level. A spark plug has a porcelain insulator, which separates it from a central electrode. In addition, it has a metal threaded shell. There are four different types of spark plug such as copper spark plug, platinum spark plug, double platinum spark plug and iridium spark plug. Copper spark plugs are standard spark plugs, which are low in cost having the least longevity compared to other spark plugs because of copper’s characteristic of getting eroded away fast. However, copper is a good conductor of electricity and therefore, copper spark plugs run much cooler compared to other spark plugs and deliver better performance, without reaching overheated temperat...
