Glow Plug Temperature --

Glow plugs may be rated by temperature, such as hot, medium, or cold. This refers to the 'burning' temperature of the plug filament (coil), which helps to fine tune engine performance. A glow plug's temp depends upon one or more of three factors: the size of the plug coil, the diameter and depth of the plug cavity, and the coating or alloy of the plug housing. Hotter plugs tend to use thinner coils, larger cavities, and silver or gold plating on the housing, and are best used with small blocks or engines running a lower nitro content. Colder plugs generally use thicker coils, smaller cavities, and black oxide coating, and are best used with big blocks or engines running a higher nitro content. Hotter plugs are best used if the weather is humid, or to bring up engine temp during cold weather and to help make an engine easier to start. Colder plugs help reduce engine temps during hot weather or help eliminate pinging (detonation).
