BEWARE FAKE NGK DENSO DELCO IRIDIUM Spark Plugs Ebay Amazon ruin your engine!! Cheap knock off clone 

Amazon should be held liable for allowing these sellers

Another way to verify is by measuring the OHMS value of them plugs. I too fell for fakes, they had outrageous OHMS values, my mpg sucked

Great explanation on comparing real ones vs counterfeit ones! Unfortunately there are a lot of sellers as you mentioned selling counterfeit parts. Another example are ignition coil packs. My 2016 Hyundai Genesis/G80 3.8 V6 uses NGK laser IR spark plugs with Denso ignition coil packs, OEM from factory. Searching for both of these items online I also noticed a lot of counterfeit Denso coil packs. If the price looks way too good to be true, no matter how fancy the packaging looks, most likely are fake.

Damn, i almost fucked up. I ordered some ngks on ebay for 17.00 for 4. Definitely gonna try to get a refund and just go to auto zone. Thanks for the info!

last time i changed my sparkplugs, i also got fake Denso that was priced half. shop said it was "OEM" which i intepret it as car manufacturer surplus or something like that, not a damn fakes!. i noticed it after i found one plugs have bent electrode so i ended up inspecting all of them real close. turns out the tip were NICKEL that shaved to have iridium tip shape!. it is way too smooth to be a laser weld!. glad i found out before installation. got my money back in the end fortunately.

I bought 4 ngk spark plugs from ebay for 19.95$ for my 1999 Honda civic on june 2022. It had 18000.00 miles on ebay plugs. It's my daily driving car. I had issue with my 69 Pontiac lemans spark plugs, so I've done some RU-vid (how to) check bad spark plugs and came to your channel. So i just got back from oreillys auto part with new ngk spark plugs, i replaced them on my Civic and check the difference between eBay and auto ngk plugs and see no difference. Then i used multimeter to check the resister and came back to 4.5 and 4.8 on all of them...and alls were nice and clean burned. At beginning there were no bad symptoms on my honda civic, it just I'm paranoia that i bought a cheap spark plugs. At the end maybe I'm feeling better now that i just spent over 40$ on Oreillys ngk plugs for my Honda.

there is a test that you'll never miss the original spark plug & that by testing the resistance by multimeter & it should give readings around 5k ohms. if they are more than 8k ohms it's fake & if it's giving under 3 ohms it's broken. you can find videos about this method

You on point with the descriptions of fake and new right on

thankyou for your info just bought a set for my kia rio off ebay and after my mate told me about fakes and they are exactly as you say FAKE,i didnt know, many thanks greetings from australia ian

I read that the resistance from tip to electrode is very different on the fakes than the real. Should be about 5k ohms.

Key tell tale is the Stamped numbers on the Nut flat. Which relates to the factory and manufacture date. Fakes do not have these numbers.

By the way, a common way to check the authenticity is check the resistance, will you able to measure the resistance of the fake one?

Bought a set of 8 ignition coils 12/22 and just replaced my second one a few days ago due to failure. So watch for fake coils.

I paid $40 on the internet for ngk laser iridium for my '16 wrx, they lasted a week and then the strap melted to the electrode on 2 of them. Caused nasty misfire. Had to shell out$80 at O'Reilly's for real thing

I got a blue box like that off Amazon last summer. They were supposed to be denso. After 5k miles i had a slight misfire so I pulled the plugs to find the electrodes melted. They were much better fakes than yours but there was no date code on the hex and the insulators didn't have the same rib pattern as the originals.

I stopped buying any important parts from Amazon or ebay, buy from authorized Manufacture approved stores, Denso site shows parts stores and Amazon and Ebay is NOT on the list

Thank you for the video, very grateful. I was considering ebay since I need 6 of them. Going to have tough it up and go to Honda dealership.

Yowser....... I have a trusted car parts business that's done me right..... I'll stay with them.

Be careful with anything you buy off of eBay and Amazon,I've had knockoffs of just about anything .you can tell by the wording of the ad if read it carefully.dont just take it at face value.

I have a hard time believing a mechanic for 20 years doesn't know the names of the parts of a spark plug. Also I think you mentioned you gapped them? You don't gap iridium plugs. You don't touch the tip.

I put a set of NGK platinum plugs in my car bought from ebay months ago, it's always had a rough idle since then and I know real NGK plugs are good so I agree something isn't right.

Good looking my boy

I just buy it from the dealership. I don't have to pay labour because i have all the tools . And each plug for my toyota is 2$ a piece. 4 of them + some toyota mobil one oil and filters. I go once a year and buy it all for 50bucks. That's all my toyota needs every year in maintenance.. I do oil change & everything on my own. My car travels almost 1000km each month, so i do it every 6months. 6000 oil change intervals have worked fine for last 11 years. It does not even burn a quart of oil. Oem is the way to go for Toyota's. Oem parts are really really high quality.

Measure the resistance.

Buy 8 pack and break one to see inside and compare it to the old one you have.

You should contact the buyers support and report the seller

15min. We are talking about a 4 banger??? Just get the cheap stuff its the same.

I got those iridium fake for my rs660 even the metal part of the original is more like goldish color i just riped the fakes into pieces

Luckily I didn't have trouble with my ngk's off amazon from 2021. The seller is G.P.S. so maybe it depends on the seller on there.

I'm sorry, but if a real plug is $15 each and you managed to find 4 of them for $15 and dumb enough to think they are real, at that point maybe the problem is you. I reason why these company are able to sell these carp is some people have no common sense. You wouldn't believe the amount of people that come to our shop and tell us we're trying to rip them off because our prices were too high and they can get it cheaper on Amazon

Thanks for sharing

We need to buy 1 plug from these sellers & link this video in a bad review!

"These ones",--------- plural and singular?

cool, but this is not Denso , mine have nothing on the nut? and the price was 15€ each

Please I need spark plugs

Amazon need to stop allowing individual sellers on their site.
