Be careful, there are people selling counterfeit spark plugs online and in person. In this video, I provide you with 8 quick checks to verify if your NGK Laser Iridium spark plugs are real.

UPDATE June 2023: Some people have been telling me to check the resistance using a multimeter, so I did. Both the fakes and the real ones were in the 4k 6k range. The difference is that the ohms from the real ones were closer (4.1, 4.5, 4.7) as long as they're from the same box. A real plug from a different box (same model) showed 6.0. The fake plugs from the same box were less consistent in their readings (4.1 and 6.0).

***The reason why these specific model ones are fake, even though they say made in Japan, and NGK is a Japanese company.... the older legit versions of this plug going back about 10 years used to say made in Japan. The company updated this model to say, assembled in the US. I know this because I bought these plugs 10 years ago. The fakes are still copying the older plugs.

The information in this video is specific to the Iridium Plugs model IZFR6K11. Other Iridium model numbers may have real plugs that use a cardboard protector and may say ///JAPAN/// on the plug.
