NGK Spark plugs

On the same topic about Denso spark plug code. Manual states W22FER9, but looks like there are no plugs with this code. Instead, catalogues show U22FER9. Is this correct?

Not sure about the ones you have shown. When I went with an iridium replacement plug a few years ago, I remember not being able to find a plug in the "7" range , but I could in the "8" range.

CR8EHIX-9 is what I use. I bought them from a motorcycle retailer online. I questioned him about all the knock off plugs being sold and he assured me that buying from motorcycle and ATV shops was safe. He said they wouldn't risk their business on selling fake plugs. Rock Auto and Amazon is another story.

Your sales person was not entirely honest with his reply to you.
I found a local shop selling NGK iridium plugs at the register. When I pointed out that the entire case of them were fake, he claimed no knowledge of them, and admitted that they just got them on line for a great deal, and were selling them because of customer demand.

I'd jump ship and use DENSO plugs instead of ANYTHING NGK lately, due to all the knock off plugs being sold out there.
Go to the NGK website and check out their "what to look for" to verify if your plugs are real or not.
Another flag is that several online places that sell NGK are not authorized to sell them, nor are selling real plugs.

Do you have a link to the info? Can’t find anything on there site.

WARNING - Beware of updated fake 'NGK Iridium IX' Spark Plugs & How To Spot Them - August 2017 (OUTDATED)

I found that but I can’t find anything on the NGK site. That’s what I was looking for.
 
I wonder how defective the fake plugs are....do they misfire, melt, or are they just regular plugs with NGK on them?
 
I’ve seen some that had shoulders, some that didn’t, some too short, and a few of them that were several threads longer than the OEM stock plugs.
Is it worth damaging your engine to find out?
 
Just because you've not heard of any, does not mean it has not happened ;)
A plug that is too long can hit the top of piston, the wrong sealing gasket can damage the head, the wrong heat range could cause pre-ignition, which can damage the piston etc.
I've seen at least two ST1300's, (one civilian model, one PD model) where the spark plug was too long and caused extensive damage to the engine.
If the plug is too short, it would probably only cause poor gas mileage, and maybe foul your plug.
I've seen a few NGK iridium plugs that caused cylinder head damage, due to really cheap sealing gaskets, and thread quality, that caused the plugs to loosen up quickly, and back out, until the engine blew them out of the head, taking the threads with them.
Wanna cut corners? Wanna safe a couple bucks?
You pay your dollar, and you take your chance.

I watched a YouTube vid where a Fake vs Genuine iridium NGK was cut in half. The fake was just crap inside, looked like an old nail had been used down the core, real rubbish. They may ‘work’ as in the engine will run but clearly nowhere near the quality we want or expect.
 
You know Bee, i am no plug expert but plugs really seem quite simple, insulation, and a place to short a charge. I get physical differences and such just wondered about functionality. I dont think ive ever heard of a problem, they are just substandard.

We will have to disagree on that comment!
The guys engine who used fake ones that were too long, and beat his piston to death, would probably also disagree too.
It’s all in just how a person takes care of his bikes and tools I guess.

But why would you entertain putting an inferior plug into your bike? It can’t be ‘just’ substandard, it’s a critical part not just some ‘add on’ or whatever like a cheapo mobile phone holder. Putting a fake set in is bad enough (if you are duped) but not even caring is another thing altogether. I avoided the iridium plugs and went for standard NGK CR8’s, paid full retail from a proper supplier and when they arrived I checked them carefully and am 100% sure they are genuine.

How could you tell they were fake without opening and examining them?
 
Really?
After opening a couple of them and pointing out all the things that were wrong, and since the entire case was ordered on line from the same place, I think it’s pretty safe to assume that they all were fake.
We did open up about a dozen of them.
