Note about brands: recommend sticking to a major brand (Champion, NGK, etc.) and from a reputable source.
Unfortunately, you can also find fakes from “reputable sources”. Hundreds of Chinese factories 24/7/365 counterfeit Champion, NGK, etc.
Moreover, in some (non-English speaking) countries the Chinese even manage to officially register the Champion brand (they first register the word “champion” in the language of the country, and then write it in English).
So you can buy a fake even in the “official” Champion store.
I found a very simple way to distinguish a fake from the original. All major brands in the USA and Japan have their own corporate colors in the Pantone system. And the packaging is printed on printing machines with the Pantone system, where each color of paint is refilled separately. The Chinese counterfeit manufacturers print everything on cheap CMYK machines, where all colors are synthesized from 4 main inks. It is impossible to fake a Pantone color on a CMYK printing press. Therefore, it is enough to bring an inexpensive Chinese colorimeter to the package and see the result. If the colors are determined as Pantone with a probability of more than 95% and their numbers correspond to the company ones, then this is an original, if not, then it’s a fake.
You don’t even need to open the packaging and look at the spark plug itself.
