WebA spark plug’s heat range is the degree to which it disperses heat. Spark plugs with high heat dispersal are referred to as cold, while plugs with less heat-dissipating characteristics are known as hot. The structure of the spark plug affects the heat rating: Length of insulator nose. Surface area. Material of center electrode. WebJan 7, 2024 · Spark plugs that work perfectly fine in 70°F may fail in extremely cold weather. Here’s why. It’s harder to generate a spark in extremely cold weather When the magnetic field of the ignition coil collapses, it sends approximately 40,000 volts down the center electrode towards the spark plug gap.

WebMay 11, 2024 · Looking at a spark plug center ceramic insulator, if the area between the ceramic and the spark plug outer steel shell is deep, that is a hotter heat range plug. Conversely, if the ceramic contacts the shell very close to the open end of the shell, this would be a much colder spark plug. WebA hot plug is a spark plug whose ceramic insert has a smaller area of contact with the metal part of the plug than a cold plug has. Hot plugs allow less heat transfer from the ceramic and thus burn off more deposits. Meanwhile, cold plugs don't get as hot. Carmakers determine which type of plug should be used in each car. tow mater house
