ngk spark plug model comparison table, ngk spark plug applicable model table

ngk is a Japanese brand as well as a world-renowned brand. Its spark plugs are mainly used in Japanese cars. The model number of the ngk spark plug is printed on the ceramic insulator of the spark plug skirt and consists of a series of letters and numbers.

The first letter at the beginning of the most common NGK spark plug model represents the screw diameter of the spark plug, such as B for 14MM threaded fasteners, C for 10MM threaded fasteners, D for 12MM threaded fasteners, etc. Detailed examples: For example, the spark plug BKR6E, BK represents the screw diameter of 14MM, the spark plug of ISO standard length, R represents the built-in resistance type, 6 represents the calorific value, and E represents the screw length of 19MM. The following is a comparison table of NGK spark plug models of some models:

When selecting spark plugs, spark plugs of the same type must be used. The spark plug type or calorific value used does not match that of the engine, which may result in unstable engine speed or weak driving. When the engine is running at high speed, the number of power bursts per unit time is relatively much more than that at low and medium speeds. For example, a V6 engine, if the engine speed is increased to 5000RPM, the heat generated in one minute is so dense, and the heat is relatively increased. If the spark plug with improper heat value is used in conjunction with the machine, the consequences will be unimaginable.
