- To see IMPORTANT pricing corrections made to video, read my "pinned" comment (at the top of comments section). This video and description is 100% my opinion of the information that NGK tech support shared with me during a phone call on 10/1/21. After much googling with vague results and watching other similar (inconclusive) CZcams videos, I got aggravated at the almost mythical why that this spark plug seems to be marketed and understood by the general public. As such, I decided to go straight to the source and grill the NGK tech support staff. In the end, no "grilling" was necessary and Tech Support was very forthcoming with the EXACT answers that I was looking for. THERE ARE SEVERAL PRICE / VALUE RELATED MISTAKES IN THE VIDEO. TO VIEW THEM, TURN ON "SUBTITLES", "CAPTIONS", "CC" or "Close Captions" -- and CHOOSE "ENGLISH (United States)" OPTION!!! -- & NOT THE "AUTO GENERATED SUBTITLE" OPTION!!! For those who are unaware, You can find the subtitles section if you hit the gear icon in the bottom right of the video as it plays ON YOUR COMPUTER -- OR -- the top right of video playing on your PHONE (in the hamburger menu).My personal notes on this phone call are expressed verbally in this video and also follow (in written form) here... "I called NGK Tech Support on 10/1/21 and they said that the marketed “extra life” that Ruthenium provides is as compared to their “basic” iridium plug (that has a 60K mi change interval). NGK’s Lazer iridium plug has a 120K change interval. So (assuming the plug you are replacing has a 120K interval) there is supposedly ZERO advantage to going from iridium to Ruthenium other than it is a little bit cheaper. I asked the rep if she was ABSOLUTELY SURE about her answer because it did not sync with NGK’s Marketing material (promoting extended life) and one random (internet board) post that said ruthenium might go 2x longer than iridium. She said she was ABSOLUTELY SURE & That the 2x longer life claim was as compared ONLY to the basic or "LOW END" IX iridium that NGK sells.
- Jak na to + styl
After making this video (and further research) It is my opinion that the ONLY reason Ruthenium is promoted is because the precious metal Ruthenium is FAR CHEAPER (to purchase) THAN IRRIDIUM!!! NGK benefits from this in 2 ways. One, (as the date I am writing this) NGK is currently the ONLY producer of Ruthenium plugs. If NGK can successfully mislead consumers with foggy marketing (convince you that Ruthenium is better than iridium) then they can simultaneously 1) steal market share from EVERY other Spark Plug Manuf. while 2) selling the consumer a product that costs NGK far less to manufacture than iridium plugs (AKA MORE PROFIT). In other words, NGK wins, but no one else does! This ALSO explains why NGK almost NEVER compares the Ruthenium stats (in marketing materials) to the high end version of iridium plugs (because Ruthenium stats are NOT superior). SHAME ON YOU NGK!!! In this video, THERE ARE A FEW PRICE / VALUE RELATED MISTAKES IN THE VIDEO. TO VIEW THEM, TURN ON "SUBTITLES", "CAPTIONS", "CC" or "Close Captions" and >>> CHOOSE "ENGLISH (United States)" OPTION!!!

THANKS FOR THE VIDEO Ruthenium plugs COST MORE AT MY AUTOZONE I THOUGHT IT WAS PRB BETTER THAN IR IT'S NOT.
Thanks for your time and effort to make this video. Hug from Brazil!
Excellent research. Thank you for sharing!
💯💯
@@microcolonel No
The ruthenium for my car are $12 less than the double iridium, and as you pointed out they have the same service life so I'll call that a win.
Same here
Thank you! i was struggling with the same stupid problem. I hadn't heard of it, then as i started researching, I quickly saw contradictory info (some said it lasted way longer, others said it didn't, others said it lasted similar just cheaper). I was leaning towards the good ol' iridium but you definitely cinched it for me. Thank you for sharing what you found!
Thanks for this video man. I was between the laser iridium, which is oem for my car, and the ruthenium. Same thing, searched all kinds of forums to see which was better in performance. Glad you took the time to make this
Iridium IX is half the price of Ruthenium HX on Rock Auto
@@microcolonel Thats because they last half as long!
God bless you brother I've been looking all over for a genuine source
Found this just as I needed it, thank you sir!
Thanks for watching! FYI... You should watch it again because THERE ARE SEVERAL PRICE RELATED MISTAKES IN THE VIDEO. TO VIEW THEM, TURN ON ENGLISH (United States) SUBTITLES (!!! NOT THE AUTO GENERATED SUBTITLE OPTION!!! ). You can find the subtitles if you hit the gear icon in the bottom right of the video.
Good to know. Did not know this. I should have gotten the high end iridium plugs. Just replaced my sister's car with ruthenium plugs.
Its very close to as conductive but better everywhere else. I used ruthenium for almost years. If you didnt know, iridium was amazing when it came out because cars were built for platinum. Right now, cars are taking iridium to its limit. It gets eaten away. Ruthenium wont. I used it in my 2015 civic si. I high spark rate after market ignition coil eats iridium plug in months. But has no effect on ruthenium. But it hit a tree so, yea. I drive a 2.5l mazda3 now and i put in ruthenium plugs right away. 2 years later. Still runs good. Will never check them, but will change them if car stutters. I'll never go back to iridium. Its just my preference, but i brought the gap down to 0.040 inches to account for the barely lower ignitability. No problem since it burns brighter at high rpms.
The voice of reason has entered the chat... ;)
Thanks for the vid. Found the ruthenium to be only 5 bucks more than iridium per set figured I may as well try them out
Thanks for the video. I was about to get ruthenium
Great researcher. I was looking for this, cause I am about to change my spark plugs, and iridium and Ruthenium and all those blablanium are driving me crazy. Thanks
U R VERY welcome!
So for prius 2006 😅 what is the best type to use
Thank you so much!
Fuckin ‘ell thanks for this comprehensive video mate! Appreciate the digging you did to 😂. Was already a bit suspicious , and thought it had to be some sort of marketing scheme; Oh well oh well haha.
I have a Tuner Hyundai and run Racing HKS/NGK racing plugs because of mid/high boost 23 psi. Going to Racing NGK/Ruthenium plugs made for a Honda Civic R are 1mm deeper and no interference and used by many Hyundai/Kia tuned cars. You can "actually" feel the smoothness difference of the Rutheniums over the Iridium racing plugs. The only bummer is the Honda speced plugs are the same heat range as the OEM Hyundai plugs. So stage 1 to stage 1.5 are as far as you want to go with those Ruthenium.
I've been using the inexpensive DENSO ITV20 Iridium Power on my 2010 Mazda 5 Premacy. Costs me only 3,500 yen or US$35 per set of 4. NGK spark plugs are nice but too pricey for me.
I see your point. But my car has few choices for plugs and the NGK iridium plugs costs $47 per plug for my Veloster turbo. Considering that ruthenium version is $12.99 and offers similar performance and perhaps won't last as long, it's a viable alternative. The thing is, this car wants new spark plugs, eats them like popsicles, like every other year. If I'm replacing once in 2 years, then things start to add up quickly with nearly $50 spark plugs and the longevity is no longer concern as long as it functions for 2 years at least. The autolite/ Ac delco and the rest of makers offer cheaper plugs, but the car runs like sh1t with them, it only takes NGK plugs as I figured out by trial and error.
Consider that I also have to get new ignition coils every 30k so far and those suckers are $120-130 per piece, this car is heavy on the wallet with just basic tear&wear parts.
Hey. Buy the Ruthenium HX PSPE ones.
The best thing ever.
My turbo audi s3 stg2 tune accepted these plugs like it was some transformer becoming a beast to destroy a decepticon.
My knock cylinder spark is 0 to -1.88 knock on open throttle.
I use the NGK ruthenium 95125
My advantage is it burns the fuel much better and leaves no chance to pre ignition spark phenomenon.
Pisp anyone who doesn't know turbos doesn't know Jack
In my opinion, you should strongly consider getting a different car (due to VERY high cost of ownership that you obviously strongly dislike). That being said, I drive a 2008 Toyota Avalon so I think it is safe to assume that we are very different drivers and car consumers.
@@miggyrocks626 did you regap them? I believe they come at .032, i have a set ready to go in my stg1 B8 A4 and was wondering if I should.
$50 per plug???? Wtf
Thanks so much for this video! I have to say I am impressed that the tech support was honest about the differences with you. I think it is also prudent to think of it as no performance disadvantage as well. That said, the price difference between laser iridium and ruthenium is pretty small for my Accord so I will just be going with the laser iridium which is tried and proven.
Basically that is my exact thought process in a nutshell (minus the no disadvantage part). The fact that it is literally unproven in the "real world", & over time, makes it inherently disadvantaged in my book.
On rockauto $9 for ruthenium vs the iridium for $7 high end
I put Ruthenium Plugs in my 2008 Miata because I don't want to ever change my plugs ever again! 😒
They work just fine. I may change them when I put 120,000 miles on them, so in 12 years! I have more important things on my mind than changing my spark plugs often! I am convinced that Ruthenium Plugs are the way to go if you want longevity. Iridium are plugs are very good also, you just have to change them more often,,,no thanks!
You were scammed. Iridium is the strongest metal in the world. It's more refractory and durable than ruthenium. Ru melting point is 4233°F vs IR 4435°F. It's also the heaviest (just as osmium).
Great video! I was trying to figure this out for a Mazda 3 and getting nowhere. Thanks!
Yes, I just spent a long time prior to making this video trying to figure it out myself and couldn't find any videos on what the REAL deal was. That's why I made this one.
You're doing God's work
My stock (intake, exhaust) VQ35HR uses 7 heat range for stock denso spark plugs, and all 6 of them’s electrodes were melted after replacing them 4 years ago with 32,000 km on it.
Do I have to use 1 colder spark plugs, 8 heat range ones?
I have no idea.
I ran Ruthenium in my Accord for a while, idk why but it seems smoother with Denso iridium tt 🤷
Interesting, thanks for posting this! I'd consider the Ruthenium for one of my vehicles where the NGK Laser Platinum isn't available, if it were cheaper - but for some reason it's priced higher than all the rest like it's a super premium part (and has a heart icon on RockAuto!). A reason the Iridium IX might have been chosen for comparison is just because it's so popular - in fact people often just say "NGK Iridium" to refer to it, not knowing about the higher-end Laser Iridium. Even though the IX only have a 50k lifetime they often go longer - and who knows if something else might go wrong before you even hit 100k anyway. Cheers.
Just an FYI. I asked my local toyota dealer about Denso (high end) irridiums that came in my car when new. Owners manual says change interval is 120K miles, but my service department said that their experience is that the plugs are good to 160K(-ish). As A result, why risk it (especially if some of the plugs on your car happen to be super hard to change)???
@@jotu2121 Interesting response... One of my cars has an OE interval of 105k but the vendor (NGK) recommends 90k for the factory plug model used. I tend to aim for the lower numbers to be conservative. Changing more often would allow you to notice a problem earlier too, so I feel more inclined to do that on my 4-cyl cars since it's so easy to check them. (If I had a V6 FWD or truck maybe I'd not wanna bother changing them for as long as possible.) An aspect I feel is hard to quantify is that plugs decline in performance at the end of their life, so if you wait until they fail you have a tradeoff there.
thank you for the legwork
You are VERY welcome!
I been tryna to compre these with the laser iridium NGK online shows it gives you more power compre to the laser 🤷♂️ so which one is better for performance
You aren't going to gain power either way, the best you can hope for by changing spark plugs is to restore the performance to closer to new if your plugs are worn. That said, I'd go with the laser iridium simply because they are proven to work well and last over 100K miles. If these new ruthenium plugs were at least as good as iridium while being much cheaper, don't you think every manufacturer would be using them by now? A couple dollars saved per spark plug multiplied by every vehicle the company makes would be a HUGE savings. But that's just my opinion :)
Pls help me out. should i go for iridium pligs laser or Ruthenium? car is honda civic 2005. TIA
Laser Iridium Plugs are the one to get
From my search i will switch to ruthinium, why? because it is said that it will have a better cold cumbustion start especially in the cold northern states, it is comparably cheaper because of less competition when all other manufactures uses iradium which results in cheaper overall pricing compare to a typical lazer iradium. Mpg may have to be test individually depending on car. The first car that i will be putting in is a 2014 subaru leagcy 2.5i automatic.
I am happy that you are happy being NGK's unpaid test "Guinea Pig" for their products. Irridium is PROVEN. If you did not read my video notes and pinned comment, you should.
So if I understand correctly, we know that laser iridium, high ignition plugs work and ruthenium is a less tested supposed equivalent that may be slightly cheaper? (For my car they are $1 cheaper)
Yes, that pretty much sums it up in general.
NGK should've priced these alongside platinum and swept the market once we found out how good they were vs iridium. Instead we're looking at their shameless money grab and shaking our heads.
Bravo! Spot, on... I couldn't have said it any better myself!!
So why when I went to get some plugs today, were the Ruthenenium plugs more than any of the NGK Iridiums they had. IX, XP, $10-$11 and Ruthenium were $15 per plug! Shoot they were the most expensive plugs the parts store offered period, from any manufacturer....
It's kind of beyond me why they feel the need to make 5 different "levels" of iridium plugs to begin with. It's honestly nothing but confusing for even reasonably educated consumers and the average consumer is legit going to have no idea. Seems unnecessary to me. Give me a cheap plug, and a good long lasting iridium and call it a day lol.
I like am gas milage up and feels more torque just my opinion
Which is best for bikes, Irridium or Ruthenium..?
Watch the video with the captions turned on, read the comments & then decide for yourself.
The best is copper. The bad is copper lasts 5ooo miles. You'll get more power from a $1.49 copper plug then a platinum or iridium or Ruthenium. Just got to change them every 3 months
i only got iridium IX and ruthenium IX available for my car. Laser iridium is so rare and expensive
Not rare and when you get twice the miles out of it not expensive either. The expensive part is the labor putting in twice as many (of the plugs you are referring to) as you would for an iridium.
I read about the ruthenium HX PSPE version on NGK website, getting better mpg and better burn/dispersion and also resisting heat better than iridium at 5,000 RPM+ since I have a engine that revs to 8,200. I figured I’d give it a shot even though my other plugs were still good. It was a night a day difference in power and responsiveness also changed synthetic engine oil, OEM transmission fluid, DOT 4 clutch fluid. So that could also be a factor.
With all due respect, you should strongly reconsider believing everything you read on a companies website as it is usually marketing fluff. That being said, it is either what you say in your comment, or you THINKING you have more performance in order to justify the decisions to spend money on the items that you spent money on (making yourself feel good about you buying decisions). Only you know what reality TRUELY is in this case.
@@jotu2121 I can feel the difference in performance greatly I also noticed before when I would floor it to 8k RPMS black smoke would come out so I figured a spark plug that has better burn dispersion would help and it did. It could just be new spark plugs but I had Iridium plugs before this.
@@guardian8319 thats funny because I am finding my Ruthenium plugs better down low. My low end torque is far better than before in Iridium.
@@jamesmedina2062 aaahahahahahhahahahahahahahaa.
Your old spark plugs must have not been working mate. There is no difference
@@DarrenBoxhall No mate. After 4+ years it is hard to rewire my brain but it is a different car now. It makes sense because the burning of carbon atoms does vary quite a bit depending on many variables. The slowed videos produced by NGK show the flames and "explosion" to be quite different between iridium and ruthenium. While I cannot tell a difference at high RPM, at the lower limits, the vehicle has more torque at lower RPM. I am sure if tested on a dyno the torque curve would be different.
I've priced the two and the ruthenium is quite a bit cheaper and they last as long or longer than the iridium
That is great, but I think that you meant to say iridium (and NOT platinum). Also, there is NO ACTUAL PROOF that they last longer (and NGK tech support does NOT say thay will).
@@jotu2121 if it lasts as long and is cheaper why not?? I never listened to marketing BS anyway
Anyone know if the purple box is good for a 3.7 q50 2015
@@jotu2121 bruh I’m talking about the left one
Ruthenium hx bro
The Ruthenium plug is smack in the middle for overall performance+longevity and smack in the middle for price. I see no problem here.
I read and do a lot of research. Personally a mechanic Engineer, I handed down on Ruthenium.
Do you know why they performed the test with IX plug? Remember, NGK rate IX for performance car which doesn't need to run up to 120k miles. All they need is performance and they tune up after every race.
IX has better performance, and don't call it lower end, lazer has better durability. NGK states that Ruthenium has been designed for both performance and durability.
I don't need to ask NGK why they performed the test with a performance plug. A normal tech could easily to figure out the answer.
You need do more research to have good acknowledge to claim anything.
I'm not sure how much better research I can do than calling the place that makes the item. Go away and research all you want I don't really have anything much more to say to you. It is what it is.
@@jotu2121 SIMP Central LMAO
All butt-hurt AF!
Hahahahahahhahahahaha
I get a kick out of people reviewing things they've never used, probably not even seen in person.
I get a kick out of people who's IQ doesn't allow them to figure out that they did not watch a review but still comment as though it was a review.
So, should last 300,000 miles?
No
Negative
Ur looking at old ngk info. Now ngk does recommend Rith over iridium. It’s depends on what model cars you look up on their website. For my car the high ignitability plugs are ruthenium and laser platinum is consider factory. Factory plugs good for 64,000kms ruthenium plugs good for 100,000kms and highly recommend for turbo engines.
My car takes laser platinum factory made by ngk…iridium Ix are not even made for my car the only options are factory laser platinum and ruthenium only from ngk. It’s a different type of metal and it does burn better and provide a higher burning heat range which turbo engines need. Higher heat lasts longer provides a cleaner burn…it’s a win win my man to go ruthenium unless ur a naturally asiperated engine then it would never matter the type of plug.
@@lukeoliver687 I understand it might provide advantages for your specific scenario. But it's just that, a specific scenario. My car, and I think most other general use vehicles, are naturally aspirated.
If you actually watched the entire video, you would know that I called NGK and talked to their customer support. They gave me the up to the second accurate information. So your claims that their info on their website is old is just wrong. And even if it wasn't, if they can't make sure the technological information is accurately updated (in a timely fashion) on their website, then they don't need to be making spark plugs.
Read my lips... I CALLED TECH SUPPORT SO THE INFO IS UP TO THE SECOND OF POSTING ACCURATE. I simply used the website to illustrate things.
Ruthenium is difficult to mold material like diamonds. The durability is where it's at. I wouldn't be surprised if Ruthenium was similar in performance to Iridium, but was more durable than iridium.
It's funny how NGKs video on these is almost opposite of what you're saying. People don't believe everyone on CZcams ask the actually source. HXs cost more for a reason! They are not cheaper.
I'm not sure what your point is. I think you might have some typos? If you're saying my video is incorrect, you have to remember that the basis of my video came from a call to the company's tech support line (you DID actually watch my video before commenting DIDN'T YOU)??? That being said I think an independent persons semi-researched / educated opinion (like mine) is far more valuable than company produced propaganda.
the rethinium plugs cost more than the laser iridium
My 2006 Toyota Corolla LE tied with Duralast Coil Packs and a Throttle Control installed, it's a fun zipper. Good MPG/Acceleration beyond stock as well.
I have no idea what the point of your comment is.
@@jotu2121 I use Ruthenium Spark Plugs on all my projects. They've been really good. A big difference in acceleration and miles per gallon. Also really depends on the conditions of all of the components and electrical integrity of a vehicle.
Thank You Very Much
You are VERY welcome!
I bought a set of the ruthenium plugs for longer service life than iridium. Pita to do on a jeep
Laser iridium lasts longer with similar features. Laser is where it’s at
If you actually watched the video, you would know that you are NOT getting the longer service life that you think you are. BUY THE HIGH END (MORE EXPENSIVE "LASER" IRIDIUMS) FOR THE LONGEST LIFE!!!!!
I bought Ruthenium plugs because I was told they would make my minivan get 350 horsepower. Did I get tricked?
Yes. But don't believe me, call NGK customer support phone and ask them. They SHOULD tell you the same thing.
I bought the Irid , and not the Ruth, because the I is 3 times better in performance, last over twice as long and is cheaper too. Duh!
Ruthenium for enthusiast performance car is a +. I love Ngk iradium used them for 10 years + on family members cars and my toyota. Ruthenium is more noticeable on igniting higher octane and high pressure injectors aplicatuons. I know this for a fact. My shop techs and I have built about 8 vw performance engines for GTI's in the past 2 years. Without a doubt from everyone in my shop and neighboring mechanics, we all know they are noticably superior. Iradium Ngk are high quality and not that far behind for practical and daily applications and the price is great.
Sorry, WRONG, YOU ARE MISTAKEN.
@@jotu2121 I have a question for you… do you own race cars or are you a mechanic… bc I have both and there is a huge performance difference when you are running 105 and 110 octane fuel or on an E85 tune, and after I watched your video I call NGK myself and talked to support and they said the exact opposite you did pal, so if you want to spread info put some facts behind yourself because this is all a he said she said and I can tell you… You are WRONG about this one. But good job fooling others if that’s what u want to do
@@nathanmeeks2846 First, I clearly state in the video discription (and probably in the video too) that the entire video is MY OPINION. Therefore, it is impossible for it to be a lie as it is MY OPINION. Just to be crystal clear ALL of my comments are my opinion also. That being said... I am willing to bet money that you did not even watch my ENTIRE video (also see my pinned comment on how to turn on subtitles for more info within the video), because (if you had) you would have seen the facts (that you claim I do not provide) clearly shown ON NGK's COMPANY WEBSITE (unless you think I fabricated an entire website for a video). In case you are unaware, NGK STILL HAS THE SAME INFO POSTED HERE... ngksparkplugs.com/en/products/ignition-parts/spark-plugs/ruthenium-spark-plugs If you actually did watch my video, then all I can say is that I wish it were possible for me to be intelligent for you... but it isn't, and you are allowed to have your opinion (no matter what it is). To be clear... You DO realize that you choosing the Ruthenium spark plug option when you play Mario Kart is NOT the same as owning your own race car, don't you? I will say that I am very happy to hear that you "have" a mechanic because, in my opinion, you desperately need one. Secondly, owning a race car (if you actually do) proves absolutely NOTHING other than that mentioning that supposed fact online most likely only serves to help your ego feel falsely superior to others. As far as you calling NGK tech support... >>> IF
Why are you so upset? You have an extreme ego problem.
@@jotu2121 Butt-hurt 101 reply LMAO :)
I read ruthenium last up 200k miles but yet it's softer than iridium
So rockauto sells ruthenium plugs at $8 -$9 a plug. You can get the high end iridium for around $5-$6 a plug. I guess all your buying is bragging rights saying you got deeper pockets to buy overpriced marketing. I bought ruthenium plugs for my mazda and she does great on cold starts but no change to fuel economy or throttle response. Ruthenium in some cases may burn cleaner in certain engines of certain compression ratios but honestly if you care about a cleaner burn you should run a water/methane system. It literally steam cleans the valves to reduce carbon build up and reduces knock.
And don't forget the feeling that you are smarter than everyone else buy buying the latest and SUPPOSEDLY greatest.
Ruthenium plugs are less than a dollar cheaper than laser iridium plugs. You would be saving less than $8 if you have an 8 cylinder engine. Kind of pointless. I thought these Ruthenium plugs would last longer than Iridium plugs. It is all marketing gimmicks. It is just a way for NGK to save on production cost and have a higher profit margin.
EXACTLY!!!!!
🫡. Thank you sir. Just saved me more money.
