WARNING – Beware of updated fake ‘NGK Iridium IX’ Spark Plugs & How To Spot Them – August 2017


PLEASE NOTE – This article was written 3 years ago so some information is out-dated!

For example, on some part numbers NGK now uses Laser Etching instead of ‘stamping’, so the font information/design may differ. The ‘line’ under the P is no longer there and the etching is thinner in the latest batches of NGK spark plugs.

Shocking Stuff

Over the last few weeks we’ve come to the attention of a new ‘breed’ of highly accurate counterfeit ‘NGK Iridium IX’ spark plugs on the market. To the untrained eye, it’s almost impossible to know the differences unless you have a genuine plug sat directly next to it. At Driven 2 Automotive, we’re always keen to crack down on non-genuine products, and these ones are easily the best fake ‘NGK’ spark plugs we’ve seen.

What’s more horrifying is the fact the seller has sold hundreds of them over multiple listings. It amazes us that the person or people in question even want to do such a thing when the liability involved is unfathomable. It doesn’t stop there, the seller even states in the listing to ‘beware of fakes’ with a link to a very old guide on how to spot them. The problem is the guide was made in the 90’s and contains only traditional OE copper (yellow box) replacements so it’s not even relevant to the listing. Deploying tactics like this is merely a way to try and boost potential order confidence by the means of fraud.

The Differences

To the left in the photo’s is the fake BKR7EIX where we’ve put it directly next to a genuine BKR7EIX (right) which we sell in our online shop. Unfortunately because of legal reasons we cannot mention who the seller is, but we can provide you with detailed photographs on how to spot the dodgy (BKR7EIX) ones.

UPDATE 15th February 2018

We’ve recently seen a whole bunch of additional part numbers being added by the seller, namely: CR9EIX, BKR6EIX, BKR6EIX-11, BKR8EIX, PLFR5A-11, IZFR6K-11. It looks as though they also have new stock in where the Iridium IX logo is far too bold on them compared to the fake plug in our photo’s. This is no surprise when counterfeits normally don’t have very good manufacturing continuity. Use our photos to see the correct sized font weight on the genuine Iridium IX logo.

        • Hi Dave,

          That’s a real shame you didn’t see our article before-hand. Just goes to show how poor the quality control is on the counterfeit plugs out there. If you ever require genuine NGK spark plugs, you can purchase them in our online store.

          Hope all goes well with the Mini
