Possible Counterfeit NGK Plug?

Got a plug off ebay…

Was torquing it up into the barrel, had barely got started on the compression washer when the whole bloody thing snapped off!

Obviously massive panic as I had the threaded part of the plug jammed right down in the plug hole in the barrel.

Anyway, managed to get that out with lots of ‘patience’ (swearing basically) and I know have a spark plug in two pieces where it should be in one.

I have fitted many different plugs into many different engines, I know how to fit them properly, this is certainly not a case of user error.

So, could it be counterfeit NGK? Or a faulty forge? Either way I’ll be sending it back and getting a replacement…

Just be careful if you go buying your plugs on the cheap from ebay! Payed about £8 fot this Iridium model in question. Here’s the listing, not essential reading… http://www.ebay.co.uk/itm/110823529052?ru=http%3A%2F%2Fwww.ebay.co.uk%2Fsch%2Fi.html%3F_from%3DR40%26_sacat%3D0%26_nkw%3D110823529052%26_rdc%3D1

Couple pics…

Any thoughts from those in the know? Or those who at least have a fair bit of experience with spark plugs and suchlike?

As always I’m grateful to anyone who replies to my topics :slight_smile:


shudda used a champion :wink:

Theres this slideshow on the web to show how to distinguish fakes - but yours has the serial number on the base ring under the ceramic so looks genuine???


The eBayer has 30k sales and judging by how many plugs he sells I would suggest it’s a faulty one as opposed to a fake.

^^^ ditto.

but nevertheless, never thought there could be fake ones on the market so thanks for the heads up. :slight_smile:

Fortunately it failed under controlled conditions and not when the consequences could be much worse!

I’d say much more likely to be faulty than faked.

Thanks all. Indeed, it seems faulty.

Will get back in touch with the seller for a replacement…

And yeah, could have gone horribly, horribly wrong had I not been able to coax out the thread!
