Different types of electrodes
Currently plugs are obtainable in different materials as well. Though the copper tip plugs are always the most usually used spark plugs, Iridium and platinum spark plugs can also be bought as well. Both copper and other plugs have their pros and cons, but one should only use plugs that are suggested by the auto mobile maunfactures
Different heat ranges
And finally, there is what did you say is identified as the operating ranging of the spark plug. It is also recognized as the heat range of the spark plugs.
The peak of the spark plugs needs to be in a specific temperature range to carry out at its best. If the tip is overheating (above 800-850 Celsius), it can lead to early ignition (aka pre-ignition). It means the air fuel mixture can ignite prematurely due to the preserved heat of the spark plug, and not the spark. If the temperature is lower than 400-450 degrees Celsius, carbon will start to placed over on the plug’s tip and a time will approach that the plug will start to pass an electric current from side to side the carbon into the body of the spark plug (thread shell) as a replacement for of the electrodes.
Spark plugs regulate the heat dissipation with the surface area of the insulator in association with the thread shell. The hot spark plug has fewer insulator area/mass while the cold plugs have better insulator mass. The hot spark plug has a slower transfer of heat away from the tip of the plug while the cold range spark plug will transfer the heat more swiftly. The heat is transported from the insulator surface to thread shell, and from thread shell to the cylinder head. Greater the insulator mass means the heat will keep on moving beyond therefore creating the spark plug colder.

Conclusion
It is extremely recommend to not play with the spark plug heat range. Companies do a massive quantity of research prior to choosing on the typology of the spark plugs as well as the heat range. Heat range not only lies on the region/market where the vehicle is launched but also the typology of the engine and appliance. When you have a stock car then the finest thing is to have the recommended spark plug type for the most favorable performance.
