Nearly all of the world's plug makers use a number-based code to designate heat range: foreign firms follow a system in which higher numbers mean colder plugs; American companies do just the opposite, assigning hotter plugs higher numbers. This is important because it determines the efficiency of plug self-cleaning and is determined by a number of factors, but primarily the actual temperature within the combustion chamber. 27 Nov. The spark plug model number is printed across this casing. Q1. Spark plug construction. Typically, the heat range is indicated within the manufacturer's part number for each plug.
