But here's the 411 straight from NGK

How do I identify fake spark plugs?​

1. Inspect font type and signs of smudges on the spark plug
2. Look out for a machine cutting mark on the caulking (could indicate a counterfeit)
3. Check the hexagon for a LOT number and the correct font type
4. The C-groove portion show machine cutting marks (could indicate a counterfeit)
5. Have a close look at the electrode. Compare to a genuine product's electrode

1. Inspect font type and signs of smudges on the spark plug
   
   Have a look at the product name on the spark plug. If the font type is different from the one shown in the photo on the left and if the font is smudged in some way, the product might be a counterfeit.
   
   

2. Look out for a machine cutting mark on the caulking ​

   
   Take a close look at the crimping portion of the plug. If you can see a machine cutting mark on it, be alert: this is indicative of a fake product.
   
   
   

3. Check the hexagon for a LOT number and the correct font type​

   
   Next, check the hexagon. If there is no Lot Number and/or a different font type is used compared to the one shown below left, it’s not an original product.
   
   
   

4. The C-groove portion show machine cutting marks ​

   
   Then look at the C-Groove portion of the spark plug. If you can see a machine cutting mark on the surface of the metal shell, again, this is a sign of a counterfeit.
   
   
   

5. Have a close look at the electrode. Compare to a genuine product's electrode​

   
   Lastly, take a close look at the shape of the electrodes. If yours differs from the left-hand picture, be warned.

All the counterfeit plugs I have encountered had an obvious physical tell.....the logo on the ceramic just above the 'nut' area appears faded and is not bold.
