May 11, 2018 · 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.

- Air/Fuel Mixture: Lean air/fuel ratios raise cylinder-head temperatures, requiring a colder plug. Rich air/fuel ratios require a hotter plug to prevent fouling.
- Spark Advance: Ignition timing has one of the greatest effects on heat-range choice. Advancing timing raises combustion temperatures, calling for colder plugs.
- Compression Ratio: Increasing the mechanical compression ratio raises cylinder pressure, resulting in higher cylinder temperatures. The higher the compression ratio, the colder the spark plug needs to be.
- Gasoline Quality: With leaded fuels, the lead is attracted to the hotter (core-nose) part of the plug, causing glazing; running a slightly colder plug helps prevent this.
Cold spark plugs are good for high RPM engines and other situations where the engine operates at a high temperature. Because they transfer heat faster, cold spark plugs can get dirty and become fouled sooner because they don’t get hot enough to burn off carbon deposits.
Automotive & Small EngineGeneral & Industrial Engines1995189117901286A colder heat range spark plug has an insulator design with a shorter heat flow path to the metal shell of the plug. As a result, less heat stays in the ceramic firing end and more is dissipated to the engine.
May 20, 2011 · In broad terms, spark plugs are often referred to as “hot plugs” or “cold plugs.” A cold plug has a shorter insulator nose length—the distance from tip to spark plug shell—and transfers heat rapidly from its firing tip to the cylinder head water jacket.
Spark Plug Basics. The primary function of the spark plug is to ignite the air-fuel mixture within the combustion chamber under any operating condition. Spark plugs must provide a path and a location for electrical energy from the ignition coil to create a spark used to ignite the air-fuel mixture.
