High-efficiency engine spark plug.The heat rating is a measure of the amount of heat dissipation.The heat range of a spark plug is the range in which the plug works well thermally. The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type. Effect of Selecting Wrong Heat Range.Heat Rating of a Spark Plug A spark plug must dissipate the heat produced by the combustion gases. The heat rating is a measure of the amount of heat dissipation. The heat rating is expressed as a number. Hot Type = A lower number: Long Insulator Nose There is a greater surface area exposed An example is: DPR5EA-9; 2887. DPR5EA-9 is the part number and 2887 is the stock number. The exception to this is racing plugs. An example of an NGK racing plug is R5671A-11. Here, R5671A represents the plug type and -11 represents the heat range. The stock number is 6596. NGK lists a design symbols chart in the front of every spark plug catalog. This means the spark plug will heat up easily and reach its optimal operating temperature. High performance engines on the other hand produce a large amount of heat, hence a high heat range (or cold) spark plug such as a 10 heat range needs to be used to resist the heat developed by the engine. Several factors influence the heat range of a ... .
