All glow plugs have the same purpose. The difference is quality! There are single coil and dual coil plugs. Single coil plugs will burn out if constant power is applied, while dual coil plugs will regulate their temperature and not burn out. dual coil regulates the plug's temperature to avoid catastrophic failures
