I just bought a set of these NGK LMAR8D-J spark plugs from a local motorcycle accessories dealer, not Amazon. And having seen a couple of YouTube videos about "fake" NGK spark plugs, I had a close look at the ones I bought.
They appeared to be genuine but when doing a resistance measurement of the center electrode, it was an open circuit. Now I never bothered to ever check this in my well over 50 years of wrenching, but it was one of the tests in the video and those NGK plugs although different from the ones I bought, measured in at 5K ohms (a resistor plug).
