In my experience, NGK perform better than Champion.

But irrespective of that debate, the knock off problem is just as relevant to Champion as it is to NGK.

But then again, thinking about it, knock off Champion plugs might be better than Champions !!
 
I had a few failures with some NGK ones fouling. They looked kosher though. I was given some Champion N7YC plugs and they've been fine.
 
My Norton always gets a miss fire in it if I run other plugs of the same heat range within a week or so but I don't have that problem with Champions N7YC plugs, I think the C means they are copper core plugs, the Champion plugs that are in my Norton now have been in there for over 6 years now with over 25k on them and they still look as good and run normally as the day I put them in, but the Joe Hunt maggie helps with long life of my plugs.
In the late 70s early 80s Champion plugs went through a bad batch of plugs and it put a lot of people off them, myself included, but they resolved that and I have had no problems with running Champion plugs, but not all plugs are the same and they all have their own problems every so often, I have always run my British bikes with Champion plugs and always got long life out of them.

As the information in the links seems to be dated and outside of the USA market, maybe I should have asked; Is there such a thing as Chinese NGK plug knock offs in recent times being sold in the west

Of course old knock off inventory could still be out there for sale. I looked over my pile of new NGK plugs and found none of the knock off indicators.
 
The sad truth is that the end user cannot usually tell where the product, not just plugs, but
many things including chain are made.

There is a hint in chain for example, old good Renold had Renold UK or Renold England stamped
into the plate, now it just says Renold.

Many cosher companies now have plants in various countries including China, India and even Turkey and
are obliged, I believe, to use local steel and we all know what sort of quality it is likely to be.

Further more there are no "made in" indications on products or even packaging. The final thing to
beware of is the term "made to European standard" as every bit of crap sold is made to European
Standard as it basically a measurement standard not a material quality.

All of you have a happy new year and thanks for the support and comments.

So true there Andy, its a changing world we live in and the the big boys wanting to make more profits by going to 3rd world countries where there is cheaper labour cost and material quality isn't so important to them, plus a lot of people don't want to pay for quality stuff, but in the long run they pay more when they have to replace crap that wears out more quickly.

You have a good new year Andy your a good person to deal with, you sent me a chain to me before you sent me the invoice for payment, very trusting indeed and I will never forget that.

ebay is good fpr a lot of stuff, but spark plugs aren't one of the items you should trust from there, and NGK in particular are copied simply because they do have such a good reputation! A genuine NGK plug is a good product.

For plugs I prefer a smaller more local supplier, like the Green Spark Plug Company (UK). But as part of my effort to avoid rip off NGKs I use Denso plugs, particularly in my race bikes. Denso seems to suffer less from the fakers! and quite a lot of racers use them anyway.
 
NGK Iridium fakes are common place in the west, not sure about the standard plugs, buy with caution - heard of two cases this year, and when side by side with an original the fake is obvious, should have used the camera on my phone when I had them in my hand.

That's pretty wild really, you cant just brew up some spark plugs in your kitchen. It would take quite a bit of manufacturing equipment.
 
I've gone through 4 sets of genuine NGK BP7ES plugs in 300 miles .( Partly due to setting up the carby )
If you measure between the core tip and the screw cap you will find they have a tendency to go open circuit . Don't know if this is just an issue with the Australian batch or whether it is a worldwide problem .

So far 300 miles on one set of Champion NY7C plugs and all good .
:D
 
How do you know they're genuine?

NGK are one of (perhaps the) biggest plug makers in the world. They should know how to make plugs that last longer tan that me thinks...
 
A while ago I had problems with NGK B8ES on my short stroke 500 single (bored model 50) which runs 10.8:1. It would kill plugs within 200 miles. Don't know what was wrong with them, they would spark in air but not under compression. These plugs were bought over-the-counter at a couple of local stores and looked genuine. I contacted NGK for advice - they asked me to send them a couple for inspection. I have not heard anything from them since (3yrs ago)
I swapped to NGK iridium BR8EIS and haven't had a problem since (1600 miles)
Go figure...
Cheers

Noticing a difference in performance when switching brands could be from a difference in heat range. Just because the chart says that they are the same, there can be differences from one manufacturer to another. Thanks for the heads up on the fakes.
