![]() It is essential to use a spark plug that fits a specific engine and its conditions of use. ![]() NGK Spark Plugs pioneered the use of a copper cored electrode in 1958, which enables a spark plug to heat up quickly and also dissipate heat quickly giving an ultra wide heat range. The spark plug temperature rises too high and induces abnormal combustion (pre-ignition): this leads to melting of the spark plug electrodes as well as piston seizure and erosion. The spark plug temperature remains too low and causes deposits to build up on the firing end the deposits offer an electrical leakage path that gives rise to loss of sparks. ![]() Conversely, a high heat range (or cold) spark plug has a short thick insulator nose which will dissipate heat much easier (above right). When a spark plug absorbs heat produced from combustion, the heat is transferred through the centre electrode and insulator nose to the metal shell, which then transfers the heat into the engine casing and circulating coolant.Ī low heat range (or hot) spark plug typically has a long thin insulator nose which will heat up easily however will not dissipate readily to the metal shell (above left). Several factors influence the heat range of a spark plug, although typically the insulator nose design provides an indication of the heat range of a spark plug. 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. This means the spark plug will heat up easily and reach its optimal operating temperature. Generally, low power engines such as lawn mowers don’t produce a large amount of heat, hence use a low heat range (or hot) spark plug such as a 4 heat range. The term hot/cold is commonly used to describe whether a spark plug heats up easily (hot) or whether it provides resistance to heating up (cold). This number indicates the thermal characteristics of a spark plug, or how ‘hot’ or ‘cold’ a spark plug is. The term hot/cold is commonly used to describe whether a spark plug heats up easily (hot) or whether it provides resistance to heating up (cold).Typically the heat range for NGK Spark Plugs varies from 2-11. Typically the heat range for NGK Spark Plugs varies from 2-11. Unfortunately, though, if a spark plug that is too hot is inadvertently chosen, pre-ignition and detonation What is the heat rating of a spark plug? If the plug is too cold, the plug will eventually foul and a misfire will occur. If you are unsure of the correct heat range to use, always start with a colder spark plug. How to determine correct spark plug heat range? In broad terms, spark plugs are often referred to as “hot plugs” or “cold plugs.”. Heat ranges are designated by each spark plug manufacturer with a number. Most spark plug manufacturers recommend that the tip temperature remain between 500° C and 850° C.
