It can be a pain when you need a new spark plug but you don't know how your current heat range translate to a new brand. Low powered engines don't normally produce as much combustion warmth so won't heat up a plug as much or as rapidly as a high BHP vehicle, therefore the plugs have to be designed accordingly so they can reach and not exceed optimum operating temperatures. A colder plug transfers heat faster while a hotter plug is slower. The spark plug heat range only indicates the rate that the spark plug dissipates its firing end heat to the engine. Well, below you will find a “heat range cross reference chart” that shows comparisons between 5 major brands of spark plugs. If the plug is too cold, the plug will eventually foul and a misfire will occur. Run hot enough to burn off combustion As a result, more heat stays in the ceramic firing end and less is dissipated to the engine. When setting the spark plug's gap for installation, use the automobile manufacturer's recommended gap. The relationship between the spark plug temperature and vehicle speed and heat range is expressed with a graph like that in the figure. For normal use, the selection of a spark plug heat range is a balance between keeping the tip hot enough at idle to prevent fouling and cold enough at maximal power to prevent pre-ignition or engine knocking. Cold plugs are used in High-Performance Engines, the heat range classification is basically the ability of the Spark Plug to dissipate heat from the … In identical spark plug types, the difference from one full heat range to the next is the ability to remove 70°C to 100°C from the combustion chamber.
