Precision of Iridium vs copper spark plugs  

NB: The best spark plug for your car is the one recommended in your owners manual. This is just a demo. A lot goes into the choice of spark plugs, it's not just about spark. Engine design plays a major role. Copper spark plugs are best for some engines, while iridium is best for others. 🙏🏼

I think a more appropriate title for this video is, "Did you know they made spark plug testers?" LOL Very cool.

I don't care about the plugs but the tester is mint 👌

Nobody: My brain: Touch it

Of course, if you use less surface the arc obviously become more "precise"

That's cool. They both make a spark.

The biggest difference is the surface area. The first reason the iridum is much smaller is because this metal is very rare and it's heat resistance is much higher than copper. So a copper tip must be bigger to last as long.

I'll take "everyone is an expert on everything" for $1000 Alex.

These both have different electrode sizes, different spark plug gaps, and are different brands. I dont know if a side by side comparison is really indicative of the performance of the material

Cool I'll stick with the NGK been using them forever and they work great for me

And now add the pressure ;)

I bet they both make the fuel combust in the cylinder though.🤔

Ngk alllll the way to the bank , it’s not about precision , it’s about how broad the ignition can be to react with the fuel, bigger ignition = more fuel burn efficiency . That’s why ngk are world leaders in spark plugs

Проверять надо под давлением

Ill take the bigger spark 🤔

Use what the manufacturer recommends for your Year Make & Engine..That's what works Best👍

При высокой температуре и высоком давлении, как в двигателе, искра совсем будет по другому себя вести.

Я свечи проверяю под давлением 12 бар, а а тут люди вообще не заморачиваются.

Copper= shorter life...but more bang for the buck

Probably why the gap is so much wider on the newer plugs is to create a larger spark for ignition. The iridium can take the heat and erosion much better than copper but costs way more.

As an amateur electrician the element metal has nothing to do with how precise the arcs are, it has to do with the tip of the contacts but what ever

It does not matter precise or not, most important things it has sparks, it has blue sparks, the rest depends on the durabilty of the tip, paladium, iridium last longer compare to copper. Copper got less mileage, the tip get shorter faster compare to paladium or iridium.

Свечи проверяются под давлением

Устройство полная ерунда!!! В двигателе свеча работает под высоким давлением! Есть специальные станки, в которые нагнетается давление, и через окошко видно как ведёт себя искра. И бывают случаю что даже хвалебные NJK при давлении искру размазывают в разные стороны, что приводит к плохой работе двигателя.

A spark is a spark. It will not make a difference it only ignited what gas is chamber no more no less if you have a gallon of gas no matter how big the spark is it will blow regardless of size of spark

Should show the ngk v-power copper plug

You've got to lick the tips for a legitimate test

Copper has always been stronger but I have to swap out frequently which is also a good thing to not let rust build up and to take a peek at the cylinders

Iridium last longer but copper actually has a better and stronger spark

The actual spark energy doesn't change much. The copper is more conductive actually.... while iridium and platinum have a much higher melting point and erode much more slowly, which is required for the finer tips. The smaller area of the finer tip provides better resistance to fouling. The higher temperature and harder platinum and iridium, in particular double iridium and double platinum are for twin post coils, where one operates in normal polarity, the reverse polarity side usually rapidly erodes the electrode and ground strap, the double platinum and double iridium hold up much better here.

Use what your vehicle calls for!! That's what is best! Iridium are very expensive compared to copper plugs & your engine will perform worse if it's not designed for them! Cool tester though.🤷

Работа свечей зажигания проверяется на стенде под рабочим давлением а это понты для приезжих

Used to use iridium until it started blowing out the spark then went back to copper and never had an issue.

I use what tje manufacture puts in them from the factory. Iridium for my literbike and platinum for my old car. Never had issues.

there is a bigger spark pattern on the copper igniting the fuel mixture sooner probably. the only reason to use iridium is it lasts longer. i wonder if you had multiple parallel circuits internal to a spark plug that could fire multiple electrodes at the same time, if that would produce better power.

Not sure what was the point but I have replaced NGK's with double cheaper Denso's plugs in my Fiat and the results are great! It has bin so about 2-3 years. I will go for Denso in future as well

You know it really doesn’t matter how precise it is cuz all you need is to ignite the fuel mixture.

I always use Denso iridium TT(twin tip). I never had problem. This allows for an extended lifespan of up to 120,000 km - more than three times that of a standard nickel plug.

Still running motorcraft plugs after 140k not even a stutter

Curious why you didn't use both the same brand, but cool demo.

NGK Iridium is the Life!!

Most of people are wrong... COPPER plugs have BEST PERFORMANCE (better for a racing/sport car because they are more conductive. Iridium and platinum plugs have much more better longevity (better for a daily car because you can use same plugs much more time/distance); but worst performance.

im going with the O E spark plug

Don't use plugs that are not recommended for you're car! You will not get better mpg, You might burn more for very little differences also you might burn out coils faster cause glitches to occur with the ecu, they run hundreds of hour's of testing and select the best plugs for the engine they build from paper to metal,

Definitely going with traditional copper

The bigger the spark, the better the combustion. Difference in material means difference in lifetime. Iridium is stronger than cooper, but obviously the spark is quite smaller...

Только под давлением!

I drive with E85 and since i got irridium sparks plug my car start way better when it’s cold outside

I personally prefer the one on the right due to more area of spark

Bro my car indica v2 petrol... Iridium spark plug Is it useful?.... Plz reply

Cool AF, I've never seen a spark plug tester.

The way the spark of the copper spark plug oscillates may actually aid in ignition

Spark plug tester??? How have I never seen a spark plug tester?

As an auto electrician I can tell you there's nothing wrong with copper style plugs for everyday engines, iridium and platinum plugs however are very durable so I like to use a crossover factory equivalent for engines with hard to access sparkplugs

Yeah copper definitely is a superconductor and definitely makes more spark than iridium but iridium is more dense so it lasts a little longer

I drive iridium always.

See some more results in RU-vid about cooper plug vs iridium plugs someone sys irdeum is good and someone sys copper is good i dont know which one is best very confused

Both great spark plugs! I always get Denso most of the times but NGK are as good as Denso! Both phenomenal Japanese spark plugs!! But get what the manufacturer recommends! Most Toyota and Mitsubishi recommends Denso! Some honda Recommend NGK! I take a Denso or NGK over Bosh or Acdelco for sure!!

И чё?

Surface area of those spark gaps ultimately affects reliability of the spark.

Видео для лохов. Вы покажите как эти свечи будут работать под давлением.

Still not as good as the Firestorm Spark Plug, which is light years ahead and won't wear out.

Troquei as velas do meu Kia soul 2012 pelas de iridiun Carro ficou muito melhor tanto na resposta quanto no consumo .

Just by what's recommended by your owners manual no need to buy fancy spark plugs you',ll have shaking issues the same spark plug cables testers 😊 are sold through Walmart or Amazon

Me: wondering how cool that would be to light a blunt with😤💨😤

Stun guns are illegal in Canada. This is brilliant! Pop the plastic cover and using public transit is safe once again. Battery not included. I would definitely go for gel pack over lead/acid though... 👍👍

NGK can last a lot

What most people wont instantly recognize is that the plug on the right will make for better combustion. The iridium plug will perform worse simply because the iridium core is undersized due to the cost, and might only be tipped with iridium. The NGK plug has a larger spark.

Denso Platinum Twin tip is good price and performance balance imo

Buji testi 14 bar basınç altında yapılır.Atmosfer basıncında yanıltabilir

Ngk spark was larger.... works for me

Iridium is extremely rare, it comes from meteorites. It almost doesn't even exist on Planet Earth.

Ngk also makes iridium spark plugs

copper has a huge fire... It has more force to move the crank shaft than iridium, Im particular of the flame size rather than materials .

Показательный тест, спасибо)

Y en q cambian las dos tiran chispa obvio q una es más grande pero es diferente el electrodo !! Cuál d las 2 sería ideal usar para cuando un auto tiene GNC o a NAFTA!!!??? Porque hacen la prueba pero no t especifican o t aconsejan cuál deberías usar !!

Everyone knows That the best candles are from denso brisk champion

iridium is more focused, but long term it will taper & fire is not optimal. no.1 remains NGK a.k.a the usual tip.

So the Copper NGK was better then the iridium ?

I use denso brand iridium spark plugs on yamaha r15 v3 motorcycle which is used for daily

I don't really like iridium but thanks for the info tho..

As long as the jobs done. Lol. No ones gonna be peaking into the cylinder to see that sparks. But cool video though.

Preformance car of course go for the good plugs. Daily driver pos stay with stock.

never seen an actual sparkplug tester. does it also test lawn mower and edger plugs that only have a spark generating magneto? thx.

Im have been use the brt Spark plug is very good

If you look closely at the two sparks the bigger looking end is the copper and the more pointy looking one is iridium , the arc on the iridium plug is in one place and consistent across the two ends, the copper plug there's little lightning bolts jumping around at random all over. Stare at it long enough you'll see it 👍

Copper puts less stress on the ignition system of cars that weren't designed for iridium or platinum plugs. ✌️

Less surface means it might get carbon buildup quickly facing combustion issues?

Very cool, never seen this before, thanks!

Детская игрушка....

I use denso irdium in SC V6 3.0L since 2005

very cool tester but it probably wont show a plug thats malfunctioning under load.

120k on my set of 4 just changed them out

Iridium's all day eeerrrrrrr day ya herd?

The NGK G power have the same pointed tip as the iridium to propigate spark the same, and seem to yield the same benefits. I run them in applications where the plug is easily changed. They seem to really make a difference in older stuff that had copper plugs. (the service interval is much shorter with the G power)

Always ohm test your spark plugs! There's a huge counterfeit spark plug market out there, your plug should ohm test at between 500 and a thousand ohms. The Chinese counterfeit spark plugs will ohm test in the hundreds of thousands.

Свечи проверяются при давлении,а без него тест ерунда

copper has a better spark but doesn't last as long

Ngk for Life

No offense, but this doesn't tell you anything - just that one has a smaller electrode.
