NGK IMR9C-9H spark plug

spanner size: 16 mm male thread [mm]: 10, 0 thread diameter [mm]: 19, 0 thread length 1 [mm]: 12, 7 thread length 2 [mm]: 6, 3 spark plug: Terminal type M4 location sparks [mm]: 2, 15 Spark plug: Iridium - middle electrode Spark plug: Outer electrode Spark plug: interference suppressed, 5 kOhm Spark plug: with flat sealing seat The combination of letters and numbers on each NGK spark plug is not only a type designation but mainly by a logical formula containing important detailed information about the function of the spark plug. & lt; BR> 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.
