Counterfeit NGK spark plugs
While doing some research, I ran across this. You can bet I'll be checking my next batch of spark plugs.

Geez! I never thought we would be able to call these things ?Counterfeit Aviation Parts?!
Thanks for the heads up Bill.

Funny, when the Russians copied the Westinghouse valves from the first nuclear powered subs, they had "Westinghouse" in the castings. Orders are orders.
Humor aside, counterfeit parts are a serious commercial problem.
Thanks for the heads up Bill. In your research, was there any indication for concern on Tempest or Champion plugs for aviation?

Thanks for the heads up Bill. I generally buy these dozens at a time since all my airplanes have them; recently when doing the pre install ohm check, I found one that fell outside the generally very tight 4k reading I've come to expect. I set that one aside and continued on until I had my matched set of 12 for the Rocket. I went back and found 3 more that matched the one "off spec" unit... I'll have to see if I still have them and check for the counterfeit. Side by side they looked identical however.

I was only searching for NGK's, so I have no idea about any other counterfeits.

I think the last couple of times I went to buy NGKs, the best price I found was from NGK directly. Pretty sure they know where their sparkplugs come from.

I can see someone in China cranking out imitation iPhones, but a $2 spark plug? How can that be worth the effort?
Also, any idea where these have been discovered? I'm curious whether NGK is addressing something you're likely to run into in stores in the US with reputable supply chain logistics, or if they've been found lighting motorcycles in Uganda...

The Chinese counterfeit everything!!! Sunglasses, shaver blades, electronics, spark plugs, EVERYTHING!!. About 10+ years ago there was a prop shop in SoCal that was installing counterfeit parts.. YES, counterfeit parts!! They got away with it until the blades came off a Travelair and killed some folks, one of which owned the Cessna dealership at Cable airport. The FAA shut them down, the owner fled back to his home country and an emergency AD was released grounding ALL aircraft that had a prop worked on by this shop. They all had to be overhauled again. Buyer beware...

You will find counterfeit products all over Amazon, Ebay and everywhere on the net. Brick and Mortar stores would be less likely to stock counterfeit products but they buy from the jobbers and they buy from the importers.... So, there's no 100% what you're buying.

and...
Don't forget the counterfeit razor blades, especially Gillette Fusion blades. Do a search to find out how to spot the fakes, before you cut the heck out of your face.
Remember, if it seems too good to be true, it probably is...
