NGK CR9E spark plug

spanner size: 16 mmouter thread [mm]: 10, 0fiber diameter [mm]: 19, 0spark plug: Terminal design M4spark location [mm]: 0, 5spark plug: Nickel - middle electrode spark plug: Outer electrode spark plug: canceled, 5 kOhmspark plug SPARK PLUG: WITH FLAT SEALING SEAT The combination of letters and numbers given on each NGK spark plug is not only a type designation, but mainly a logical formula containing important detailed information about the function of the spark plug. With this formula, NGK has standardized its entire range and is thus clearly able to determine the specific properties of the respective products. This again simplifies the handling and correct selection of NGK spark plugs, both in the original equipment at the manufacturers and later in the shop, workshop and customers. A typical designation is: The combination of letters (1-4) before the thermal value gives information about the thread diameter, the size of the hex key and the type of construction. 5th position (numerical value) indicates the heat value. The 6th letter indicates the thread length. The 7th letter contains data on the special design features of spark plugs. The 8th position is again a number in which the distance of the electrodes is coded.
