What is a hot spark plug?
For low compression engines and engines with problems in complete combustion, hot spark plugs are better. On the other hand, for high compression engines like turbo and superchargers, and nitrous and high-performance engines, cold spark plugs are preferred.
A 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.
May 11, 2018 · Hot vs. Cold Spark Plugs. Let’s first define what is a hot versus a cold plug. 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.
A spark plug's heat range is the degree to which it disperses heat. Find out what the appropriate heat range is for your particular spark plug!
Automotive & Small EngineGeneral & Industrial Engines1995189117901286The spark plug heat range only indicates the rate that the spark plug dissipates its firing end heat to the engine. A hotter heat range spark plug has an insulator design with a longer heat flow path to the metal shell of the plug.
Jul 10, 2020 · What spark plug heat range should I use—10 factors that influence whether you need a colder or hotter spark plug for racing and street applications.
May 20, 2011 · Heat range is the speed at which a spark plug can transfer heat from the firing tip to the cylinder head water jacket and into the cooling system. Choosing the right heat range is crucial for high performance engines.
