Spot the Fake: Spark Plug

[@VxO4fame]

Wow at least Denso released an official vidoe how to identify them. I am still waiting on an NGK Video.

[@kalundra9345]

Denso is better than ngk Believe in me 😁

[@rondhole]

@@kalundra9345 No, they are very close and similar price as long as the same grade (Iridium, double platinum, platinum, Copper). I will go with Iridium that cost about $10 a peace and can last more than 120k Miles. It is important for V6 transverse engines since it is costly to remove the intake manifold to get the rear 3 cylinders.

[@VxO4fame]

@@kalundra9345 Yeah i am not argueing with that. 2 NGK Plugs already failed me. And i am talking about their so called iridum laser series after 20.000 miles

[@zuppagraves2945]

My suggestion is to only buy them at the dealer, since this video was made some of the knock-offs now look exactly like the real thing. They last over 100,000 so why save $20 - $30 and risk ruining your engine?

[@ПетроВенгель]

The significant differences between fake spark plugs (in my case, this is DENSO SC20HR11 IRIDIUM) from the original are as follows. The central electrode did not have a laser-welded iridium washer/cylinder, and the side electrode had a stamped imitation of a "welded" resistance welding disk. These differences between the fake spark plugs and the genue spark plugs can only be seen using a binocular microscope.

[@alvinlawanto]

Hello may i ask this? Do you manufature denso product in your country? If yes, do you make from scratches or you just assemble in your country using the parts from japan? And do you write "made in japan" or made in your country..? I hope you understand. Thankyou..

[@nathanielramirez8997]

We have a group chat trying to identify some fake plugs, specially IQ24s where I received one with gold terminals and they have other colored terminals as well as some suspect laser marking and differences in our stamps

[@PeterSmith-ls7ut]

Did not know they fake spark plugs. Just bought some denso plugs from , Halfords for my citroen c1.

[@jalee6587]

I got some knock off ngk platinum spark plugs looked good. Ran fine. But what happened is they were already worn out at 25k miles.

[@grominwithrob1339]

So I bought 6 denso tt plugs from Rockauto for my GMC Sierra and picked up the other two from AutoZone. I installed them and started having random misfires on the 6 cylinders with the "denso" plugs from Rock Auto and the two cylinders with the plugs from AutoZone were fine. I pulled all the plugs and put my old AC Delco iridium's back in and zero misfires again. I will be contacting Rock Auto over this crap. I have pictures and videos of the 6 cylinders randomly misfiring as well as a video of zero misfires with old Delco plugs reinstalled. I gathered data with my bi directional scan tool and my HP Tuners software.

[@elmakednos]

Is WUXI-DENSO plugs, original? I have an old japan one and a Chinese WUXI-DENSO and I see some differences.

[@prototype8888]

got seller claiming bluish electrode around tip is original..is it?

[@chadi6536]

Hello Sir my car.corolla s 2013 owner use denso only i put njk spark plug is corret or no?

[@skip741x3]

just recieved some iridium ik20l 5358 plugs... they Seem legit, no odd gapping,proper packaging, iridum tip looks like the darker metal and very fine... BUT the welds on the curved electrode are Atrocious, I mean on some of them Im actually worried about even risking installing these lest the electrodes fall off!.. Looked like they were welded by some kid in his 1st welding class..I was expecting beautiful HQ welds on the iridium especially... is this normal and just a bad batch maybe?

[@densoaustralia136]

Hi @Skip741 x, Thanks for your message. Our manufacturing process includes some pretty vigorous testing and zero child labour, so if the weld looks dodgy then something is amiss. Send us some photo's (via www.denso.com.au or our FB page), we will take a look and let you know.

Amazon -Official dealer of DENSO®

[@skip741x3]

I had no idea this crap was going on till i went to buy some denso platinum tt's on amazon, read the comments, and saw people talking about fakes....wtf when u cant even rely on amazon to ship u the real thing...almost makes me move to another brand becuz i dont know where to get the real thing

[@densoaustralia136]

Unfortunately, they sneak in everywhere. The safest option is to check our website and order from authorised stockists.

[@bobdebouwer7835]

Anyone can sell on amazon.

[@leonguyot4991]

.Sorry Mate, I'm not going to get my plugs in Australia or New Zealand! (I live in the USA and that would be a tad inconvenient)

[@LykeArgy]

My "denso" SK16HR11 have thickness of 0.69 , 0,72 and 0.84

[@isaacchimebuka899]

How can I have one

[@kamrulhassan7185]

I bought from an authorized Denso reseller and the plugs look severely burnt just after 5K kilometers.

[@densoaustralia136]

Hi Kamrul, It's difficult to assist without knowing all the details, but to begin we'd suggest visiting our website and entering in all of your vehicle details to ensure you have the correct plug for the application. Vehicle modifications can also alter the plug you should use, and also if the car is used daily or for racing.

[@g.n8047]

its not possible anymore to see the differences. I have fake ones and genuine ones in my hand and seems like the same thing. Both same finish and elements that Denso says to check. I'm only sure about the genuines cause I've bought that from a Nissan dealer

[@densoaustralia136]

Unfortunately, the effort to replicate the plugs is only superficial. The best bet is to always buy through authorised channels (visit denso.com.au for a list of where to buy).

[@nwobodonwebonyi3331]

Wow I really love 💕 this please how can I get this please?

[@SLDriver]

Very Informative...

[@bobdebouwer7835]

This video is so short. Is this all you have to say about it? There must be more ways to tell.

[@cisco00079]

Seems like I got real ones in fake boxes. I ordered on ebay

[@Asian_Connection]

With your help the fake parts looks identical now.

[@IcarusTECH]

Holy volume variations... :/

[@jojo-jj]

Both looks real to me ... maybe made from different country, but both are genuine denso ...

[@densoaustralia136]

Hi Mikel LL, Unfortunately the one on the left is not genuine. As explained in the video inferior materials have been used along with substandard manufacturing techniques.

[@balrog006]

Wow, doubting the actual manufacturer on an official video where they explain to you how and why the fakes are fake... brilliance.

[@jojo-jj]

@@balrog006 If you buy those from AMAZON, is amazon an authorize dealer ? After watching this video, if the vendor only show you the fake one, can you still tells the difference ?

[@JeritanKematian]

Unhelpfull videos ever.

[@densoaustralia136]

Hi azarul areffi, what type of information would you find useful?

[@allknownful]

@@densoaustralia136 Hello. Im having trouble with the russian denso support officials. They are refusing to provide the official documentation of the fk15br-al. All i want is to simply compare with the ones that were sold to me, presumably original. I have a feeling that im being fooled and want to see the official characteristics and the external look of different plug parts, Is that possible? Is there any email that i can send the photos to?

[@LykeArgy]

I saw a video on NGK sparkplugs and testing them with an ohm meter , also it had part number on the actual nut of the plug (but before i go buying an ohm meter /multimeter) i'd like to know if originals have markings on the nut like NGK does ?? @@densoaustralia136
