How to Spot Fake NGK IZFR6K11 Laser Iridium Spark Plugs

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 NGK Iridium Plugs model IZFR6K11. Other model numbers may have real plugs that use a cardboard protector, may say ///JAPAN/// on the plug, and may be manufactured in Japan or Thailand.*** ** FYI -NGK manufactures in Japan, US, and Thailand. Some models come with plastic covers and other models come with cardboard. Main places you should be worried about fakes is Ebay and Amazon 3rd party sellers. For a full list of locations where NGK Manufactures spark plugs, click here: https://www.ngkntk.co.jp/english/corporate/networks/index.html In the video, I show you how the real NGK plugs for this model number are engraved with the words, Assembled in USA from Japanese parts. During the pandemic NGK was also making this model plug in their Thailand plant. Aside from eBay, these fakes are also sold on amazon through third party sellers. When you buy stuff on amazon, it tells you SOLD BY and SHIPPED BY. As far as I can tell the NGK Laser Iridium plugs on amazon are all SOLD BY third party sellers. Amazon has an FBA program where third party sellers can send stuff to their warehouse to sell on amazon and amazon will ship it out to the customer. Don't confuse the SHIPPED BY amazon prime as being SOLD BY amazon. Known good Amazon 3rd party seller: AUTOPARTSAAA, CPS, OverStockDirect Places to buy legitimate plugs: Auto Zone, Napa, Pep Boys, O'Reilly, Advanced Auto Parts, Parts Authority, Summit Racing, Parts Geek, Parts Plus, Rock Auto.
