slashesFake or not?

Have you ever bought a product from a well-known brand and realised afterwards that it’s a counterfeit? Unfortunately, as with many premium products, this could even happen with parts from NGK SPARK PLUG. In fact, the company’s Technical Service centre recently became aware of fake CR9EIX spark plugs that caused engine damage due to melted centre electrodes. NGK SPARK PLUG would like to put its customers on alert and has put together a 5-step-guide on how to distinguish between original and fake products.

Have you ever bought a product from a well-known brand and realised afterwards that it’s a counterfeit? Unfortunately, as with many premium products, this could even happen with parts from NGK SPARK PLUG. In fact, the company’s Technical Service centre recently became aware of fake CR9EIX spark plugs that caused engine damage due to melted centre electrodes. NGK SPARK PLUG would like to put its customers on alert and has put together a 5-step-guide on how to distinguish between original and fake products.

A study published by the European Union’s Intellectual Property Office (EUIPO) shows that the loss to the European economy created by the presence of fake products amounts to 60 billion euros per year – equal to 7.5 per cent of European sales. Not to mention the individual harm caused to customers who were cheated.

But does it really matter if spark plugs are original products? Yes, in fact it does. NGK SPARK PLUG’s Technical Service team recently became aware of cases where customers bought CR9EIX NGK spark plugs on the internet, which proved to be fake products. “These spark plugs melted and caused damage to our customers’ engines, which is annoying, costly and avoidable”, says Kai Wilschrei, Manager Technical Services Aftermarket EMEA at NGK SPARK PLUG EUROPE.

What’s the difference between the original and the fake?

“Original NGK CR9EIX spark plugs have a centre electrode with an iridium tip. This material has a very high melting point and is extremely hard and long lasting,” explains Kai. “The fake plugs, however, do not have any iridium on the centre electrode. They feature a standard Nickel electrode that was tapered down with a lathe, giving it the same optical impression as the iridium tip,” he continues. “This fake part is very weak and can’t stand the heat. This soft spot causes the centre electrode to melt, inflicting damage to the engine.”

 

What to do if in doubt?

Here is some expert advice from NGK SPARK PLUG’s Technical Service team: “If you have doubts whether your part is original, follow our 5-step-guide. Refer to the following images and compare each one thoroughly with the suspect product.”

1. The branding

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. 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. The hexagon

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

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. The electrodes

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

What to do when you spot a fake product?

“NGK SPARK PLUG recommends that you always buy from a retailer or supplier you trust. If you have already bought a counterfeit item, take legal action”, the expert concludes.
