It is possible, with care, to decode the construction of NGK spark plugs. This can help in identifying suitable replacement parts from NGK or even equivalent from other manufacturers. We would not recommend using this as your sole method of identifying replacement parts unless you are confident in using the decode.
Below is NGK's spark plug part number decode. This applies to standard copper and platinum plugs. There are additional decodes available for NGK US specification plugs.
