Counterfit NGK spark plugs Has anyone had "fake" NGK plugs sold to them? I had no idea such a thing existed. I purchased 8 plugs from Amazon and I am not sure now if the plugs are authentic NGK's. I called NGK - USA and spoke with a tech rep. He said he could not tell me if the plugs are authentic or not as the illegitimate manufacturers are getting very good at recreating the fake plugs.
He suggested I only purchase plugs from an authorized NGK reseller like auto parts stores, Summit, Jegs, etc...

Could be fake, Anything can be faked anymore razors/fuel pumps even tires..... Many times they come off the same assembly line but use inferior materials. That's the problem with having products produced in other countries you don't have control of your own product.

Initially I was concerned that if they were cheap knockoffs that the ground electrode might fall off or the porcelain might crack apart in the cylinder and ruin my day! 
I think these are genuine.

Bingo. As was said somewhere else around here, the Chinese will make parts as good as the buyer wants them and pays accordingly.
Probably five times that for iridium.

I just happened to see a youtube video about counterfeit NGK plugs, so I looked at the plugs I purchased and the printed NGK on the plugs were not centered on the porcelain. Then I noticed what I thought was a poor weld at the ground electrode. Turns out they are exactly like the ACDelco plugs electrode.
I called NGK and spoke with a tech rep,but he could not tell me if the plugs I bought were genuine or not. After some more time spent on the internet , noticed that all of the pics of the NGK tr6IX plugs looked just like the ones I had. All in all I feel pretty confident these are good to go.

I just get mine from autozone or whatever local parts store has them. And your big name stores will be getting them from the manufacturer so you should be safe if you stick to that.
Always remember, if the price is too good to be true, then there's likely to be a problem. NGK plugs are high quality and even at full price they aren't that expensive. The copper plugs are like $2 a piece even from brick and mortar parts stores.

IMO one of the main reasons one should be upset about counterfeits (of anything really) is warranty.... imagine having something for months then it dies, you go to call the manufacturer to get a replacement and they get to tell you that your product is, in fact, a counterfeit when they can't find the serial number in the system.
