Iridium Spark Plugs vs Normal 

I agree and so does Scotty for that very reason.

@@TheMapkiss yessir

The back 3 in my V6 are hard to get to, so iridium , the front 3 normal plugs.

@mvnorsel6354 Personaly, I keep thing uniform so when I changed them, I did all iridium.

@@mvnorsel6354 cheap scate 😆

6 hours? For you or the tech?

@@abdul-kabiralegbe5660 My guess is for him, it isn't a simple job on many V designed engines in FWD vehicles, as half of the plugs are up against the firewall, you often have to remove the intake. Some people will try to do it without removing the intake, often costing more time than just removing the intake to get easier access to the plugs. People will also often overlook the idea of the intake removal before starting the job, so they don't have replacement gaskets on hand to put in the intake when putting it back on, then you have the choice of either using the old intake gaskets (not ideal), stopping and going to get the gaskets (good idea), or - if they already took out the front 3 plugs - putting old plugs back in to get the gaskets or trying to finagle around to get the rear 3 without removing the intake. A good tech could do it within an hour, but they already know the procedure and are familiar with it.

I'm not a pro, but it took less than one hour to put plugs in my wife's 09 3.5 V6 AWD Edge. You don't need to disconnect everything from the upper intake - just unbolt the manifold and unplug stuff on the right side only and bungee the intake up to the hood on the left side. Make sure to put shop rags in the intake holes and change the intake manifold gasket. There's a youtube video showing how easy it is. Same with the 3.0 V6 Escapes.

*too

You're correct, same for all fluids.

sir, my car came with normal copper plugs but when I switched to iridium it showed some improvements like engine is less stressed than copper plugs and mileage has improved marginally but many forms has suggest to stick with oem plugs but may be they didn't gave iridium plugs pre installed because they are too dam expensive than the copper ones ... it's my assumption and personal experience with the plugs please do share your experience 🙏 thanks in advance God bless

@@mrcoolhellyeah252 There is truth in this when it comes to manufacturing anything, the balance between being cutting edge and cutting costs. If it can save them 60 cents per car if they use copper instead of something exotic like iridium, they're going to do it because it's going to save them millions across the total volume of vehicles they make

@@IronMan3582 thanks, I was curious before changing the plugs weather iridium can make a difference and now it's been almost 2 years with the iridium plugs running the car sometimes I still get stuck in feeling that maybe the cooper ones were best for me as it's a petrol car and in my city heavy traffic i barely get 10kmpl with ac onn 🫣 sorry for bad English,, such mileage make me think was it a good decision or not but the information on this topic is very limited and it's mostly not a concern for many who buy the car of honda or hyundai or suzuki brand as there engines are very refined but I have tata car with 3 cylinder engine with 5 star rating build ncap which stresses out the engine compared to other cars... Anyway thank for replying to my reply 🙏

Yeh. But diesel engines 'fire' whenever they are ready instead of when a tuner sets them to fire. Thats a bit crappy, really.

What's "crappy" is people who have no clue about mechanical engineering, but make comments such as yours. If you had even a basic understanding of internal combustion, then you would not have made such a fundamentally silly comment. Pick up a wrench Melody, and maybe you will learn before you make yourself look ignorant.

You mean glowplug

No, he meant spark plug - sarcasm - you missed it.

@@herbieschwartz9246 I got it. But you missed that diesel does not ignite at the same piston position. Thats also why some 'rattle' when ideling.

NGK has their Ruthenium HX spark plugs. They are amazing in my old 2008 Ford Focus. Smoother performance and great fuel millage. Take care all.

Denso tt Iridium are best for Toyota

My Rambler Ambassador came with Baberuthenium and lasted 714K miles..

As detailed, the threads are rolled, so anti-seized isn't needed. I still apply a small amount of anti-seize on the threads regardless for this exact reason.

The upside of iridium is that you'll change em way less often.

Just use a correct torque. Don't use anti-seize, since it will increase the torque applied. It's not complicated.

What bike? Is it okay to change spark plugs as long as you maintain the gap mentioned by the company? I am thinking of getting the iridium plugs for my 2011 alto k10 but nervous To do so if it damages the engine in some way.

It will be fine. I wouldn't gap the iridium plugs. I just bought some for my 2003 suzuki TL1000R, I will put them in tomorrow. It has fresh NGK dual electrode plugs but everyone on the forums say the iridiums are the way to go.

should of bought a honda.. takes me less then 5 mins and one tool

Why does this matter when the iron or aluminum block have lower melting points? No engine is ever going to get that hot. If it does, you're going to have much larger problems than failing sparkplugs.

@@joshuapayne8811 what ignition center temps have to do with engine temps?

The only thing I've noticed with a improved spark plug is MPG. That is something you can look forward to if you get the right plug that it needs.

Probably zero unless there was something wrong with your old set of plugs.

the difference is about $15 per plug. just use platinum plugs they work fine and they last a long time.

So what's the issue? You're good for 100K miles minimum.

Top plugs from mfg are pre lubed. Part of what you pay for... Note, aluminum heads.

Thinking doesn't make it true.

And check the Price on OEM spark plugs. The price isn’t so bad on those

Best advice 👍

I believe they last anywhere around 100k miles. They’re the go to if it’s a pain in the ass to access your spark plug for replacements

Yea like I’m any boxer engine 🫣

just ask your mechanic to see if it's still good. my last one went to 92..000km, the double iridium.

If in doubt, then replace the plugs. They are not very expensive when you actually think about it, 100K and you have your money's worth. In that time, you probably have (or should have) spent a lot more on condoms and alcohol than a set of quality plugs.

Oh wow, a Diesel troll in a spark plug debate. Haven't huffed enough fumes to go to sleep yet today? Your Cummins is shit too, don't worry.

I was hoping to elicit a silly comment from a gas-sniffer, and was even rewarded with him (her) openly making themselves look ignorant on things mechanical. Thank you and congratulations.

wait until you injectors it's just a matter of time

Yes, they lasts but conductivity of iridium and platinum are lower than copper.

Yeah if you want them to last longer without changing them, at the very least.

Sure , I’m running iridium in my 2006 fiesta st

@@savyor1839 thanks for replying

@@choncoconcos5912 enjoy ))

you can change plugs in any car, just make sure it works.

You have to buy an extended warranty first . . .

Plugs made with Iridium do not increase cylinder temperatures. Iridium can withstand increase cylinder temperatures compared to copper all the way through to platinum. NGK has Ruthenium plugs, but I have no knowledge of the benefits of those compared to Iridium plugs.

No because the spark plug doesn't affect engine temperature.

Horses were 'better' according to some.. ... even though they deposit Horsehit everywhere.

problem is you almost never have the issue of "not a big enough spark". You are correct about the conductivity, but sadly it doesn't really matter in everyday vehicles.

Coils only induce enough voltage to overcome the resistance ( gap ) in the circuit ... if as you say copper is the better conductor less voltage will be required to jump the gap .... If you want a " Bigger Spark " increase the gap .

The copper core has ZERO measurable effect on spark voltage. The copper core (inside the nickel alloy electrode) is only there to transfer more heat from the electrode end to the shell to reduce erosion. That is it! No other reason. In case you have doubts, I've been working for a major spark plug manufacturer for the last 20yrs. I know what I am talking about.

At 30K volts, the fractional resistance difference between copper and any other metal is literally meaningless. Some spark plugs use 500 ohm resistors for radio noise suppression with no loss of performance so a 0.01 ohms difference between the electrode material makes no difference at all.

You can replace the Leaf with a Maxima and then put the new plugs in that. It's way cheaper than replacing the battery in the Leaf.

@@katieandkevinsears7724 my wife loves her Leaf, the battery's fine but just wanted to change the spark plugs...oh darn, I couldn't carry on typing without 🤣🤣🤣😂🤪

It was all the oil, I to have a 69 Bonnie🎉😂

Dyno results disagree

Great thought just you forget it last longer that mention in the video also...

Iridium spark plugs are more durable, generally at least twice as durable, than standard copper-nickel spark plugs. They improve combustion (dyno tested) leading to marginally more power and improved emissions. They are less prone to fouling and work better at idle. It‘s not a placebo product, iridium plugs are legit and in many cases even cheaper in the long run, they might cost twice as much but they can last well over twice as long. Edit: and you generally don‘t need to gap them, one less headache to troubleshoot

@@SahnigReingeloetet man in india the price is 4 time than the regular plug

@@HimanshuSingh-st8nn then it‘s not worth it man

Two weeks ago, I bought 6 Bosch Iridium spark plugs and each gap was different. Only one of them didn't need to be adjusted.

Bosh parts seem to be hit and miss even in original parts. i had ignition coil crap out at 80tkm and cam positions sensors crapped out at 90tkm. i still occationally drive 1999 nissan that is still running on original coils at 360tkm and original plugs till i changed them at 340tkm. Wasnt much left of the spark materials but somehow they still worked haha.

@@imrileth6618 Bosch does what so many other name brand companies do, they order parts from vendors and just have their name added to the product. Hit and miss quality is often the end result. What is worse is there are counterfeit parts too.

@@imrileth6618 Bosch seems to be hit and miss because they often have vendors make parts for them with the Bosch name added. Worse still is counterfeit parts.

Graphite, copper or bronze powder based grease will surely protect any thread from seizure.

@TransAmDrifter Possibly. I cannot verify that but hopefully it did. Part of the problem was a cast iron head with exposed plug recesses which attracted dirt and moisture.

I've got the same setup. A very nice and healthy 3 cylinder that tends to surprise quite a few people if/when I decide to step on the throttle. :)

Non-resistor plugs can cause EM bleed into sensitive electrical components. Use what the manufacturer recommends.

@@herbieschwartz9246 Bullshit

Not where I buy them do they cost 10 times as much. Around $12 each for popular brands. Change your store.

it's ok to use other sparkplug like iridium sparkplug for longlife than stock sparkplug.. Nothing will happen

@@FryTofu it's not ok,it will mess up your motor, your motor will not run right as like the factory

@@FryTofu GM vehicles uses acdelco spark plugs iridium

Please explain??? If you put the wrong sparkplug as far as heat range or to long yes. ​@@lifegoeson4085

It depends. A lot of times manufacturers offer an iridium equivalent to the OEM ones. Especially NGK, they are the same plugs just better.

😂😂😂

This is done in aviation reciprocating engines - they clean and rotate spark plugs.

It's the Harley that's the problem. Archaic, outdated, overpriced, underperforming. Honda lawnmower has more engineering than a Harley.

@@tchelby ok hot rod

That’s probably for your vehicle

no thats probably the way a car should be maintained. its like installing a 150 watts door speakers into a car with a stock head unit thats made and tuned to play with the stock speakers, unless you upgrade your headunit to make it compatible for your upgraded speakers.

@@scottykilmer3920 again that’s probably just your car my guy , you don’t know what I got under my hood that’s why I said that’s probably just u cause it works fine for me lol

@@Patsan4ik1 you sure it were original parts? Lot's of fake stuff is sold everywhere.

Either there is a spark that ignites the fuel/air mix or there isn't. As long as it sparks every time, it's going to work. I've taken decades old spark plugs out of engines that still work fine. Garages used to clean them and put them back in.

@@Spiritof_76 100% my own experience!

You seem to know more than chemistry. What a sweeping statement to make. I wish you had adequate knowledge at least

@@colsanjaybajpai5747 Lots of cars making incredible horsepower from the 1960s on didn't have iridium plugs. The rest of the ignition system is just as important. Perhaps paying $12 for a spark plug rather than $3 has benefits to sellers more than buyers. As long as there is a reliable spark, the engine runs fine.

@@colsanjaybajpai5747 As a mechanical engineer, with a large, nearly 50 years' experience as a very successful tuner of racing motorcycles, both 2-stroke and 4 stroke, and as a technical editor of various motorcycle magazines, I know what I'm talking about - which you don't seem to. Spark plugs don't have the slightest influence on performance, period!

What's a rip off? Explain what you mean or don't make a comment at all.
