Is this a Fake Sparkplug?

[mohammad]

Im sure fake plugs exist, just printing some text on a random sparkplug and putting it in an old OEM box is enough to fool most people. If you had a spare spark plug you could probably tell if its fake by measuring the hardness of the tip. maybe something like a nail file would do the trick but this would probably require you to sacrifice a real OEM plug to compare your results to.

but what can you say about the tips of both SP? why are they different?
so how can someone be sure that what they got is not a fake.

From any manufacturer, "we reserve the right to change the product any way we see fit and we don't admit liability or will we update your older car with new spec parts. We do this to make a better product, make more money, or in the case of Hyundai simply to amuse ourselves."

I changed your wording ... for a touch more accuracy.
