iridium spark plugs? NWS!

[Roninmedic82]

What kind of benefit would I get from iridiums? I'm gonna put them anyways and I will find out soon, but should I look into rebalancing air/fuel mixture with this product? Keep in mind, I'm not asking someone who only rides in a 240 or an altima(no offense), I wanna know from someone who rides in a Z and has used these plugs in their Z.

and now.... I will have the IT manager crawling up my *** for that pic. Edited by Administrator.

spark plugs will not make any appreciable difference, and certainly will not require any tuning

u disgust me

Better spark plugs should not affect a/f ratio. All it will do is deliver a cleaner combustion cycle.

I understand that you have no desire to use your pen15 for its actual purpose, Richie. But you're entitled to your own opinion. I personally think that the picture is quite pleasing rather than offensive.

Dude....Your fu*ck*n lame! if it does offend you, I've accomplished my goal.

Iridium Spark Plugs

Iridium is a precious, silver-white metal and one of the densest materials found on earth. The natural properties of Iridium offered NGK the opportunity to create one of the world's finest spark plugs. The result are spark plugs that require less voltage to spark, burns fuel more efficiently, sparks at leaner air/fuel mixtures, and delivers higher horsepower and better gas mileage.

NGK offers two choices of this precious metal plug:

The Iridium - A high quality iridium plug installed as original equipment (OE) in the automotive industry since 1994, and the new Iridium IX® - The ultimate evolution of a performance spark plug.

-Engines with 100K tune up intervals usually use Iridium spark plugs-

Can't go wrong with them. Make sure you set your spark plug gaps to the correct specs.

hey mike, you seen any numbers / graphs as far as actual gains over baseline with these? im betting with a stock VQ theyre pretty minimal if any, but still like to see

as for the eye candy you guys are gonna get me fired lol

I'm just gonna say you're wrong and suggest you do a bit of research to find out why

Evil, youre one of my favorite mods, why you being a d*ck? If I am wrong can you just correct it, instead of being all omnipotent about it.

thanks

just an article regarding iridiums

Per the Nissan website for the Z, the Z comes standard with iridium tipped spark plugs...

[evildky]

lol, not being a prick, just being myself I already answered the question in my first responce, I just get tired of all the spark plug threads, people looking for something for nothing, it's a spark plug, it's purpose is to ignite the fuel and air that are being compressed, it won't make more power, your power is limited by the amount of fuel and air in the cylinder if you are looking to add power look to add air and fuel

IR is actually not a very conductive metal, silver would be the most conductive, but it can't survive, the heat, platinum does have a higer resistance than IR, IR is the hardest element known to man (actually a tie with osmium) it is the most corrosion resistant metal known to man as well

copper plugs were used for the same reason as copper wires, it's a cheap good conductor ant can take the heat, pplatinum was added later because it lasts far longer than copper even if it has higher resistance, and not IR has less resistance than platinum but an even longer lifr, copper is still a better conductor but it won't last, I run copper plugs in my race cars, i replace the plugs anuually which is generally under 1000 miles so they don't get a chance to wear out

because iridium is so hard they can make the point of the electrode tiny, the theory is that it's easier for the spark to jum the gap form a finer point, the problem is that the smaller point is also more likely to become a hotspot and cause preignition, this is why racers will polish the combustion chamber of a cylinder head, to get rid of any potential hot spots

also note, platinum plugs do not fare well with nitrous, nitrous breaks down the agents that hold the platinum tips on

this si why I didn't want to go into detail, because I know it would take me forever and look like a biograpphy

here's some readinghttp://www.babcox.com/editorial/cm/cm120032.ht ... i/E...page)

lol, not being a prick, just being myself

that's not you!!! The post you made above is more of an Evil post. thanks. I rather have an abundance of information than the lack of.

p.s. I didn't even notice your first post because I had to scroll away from the picture fast.

you is right.

because iridium is so hard they can make the point of the electrode tiny, the theory is that it's easier for the spark to jum the gap form a finer point, the problem is that the smaller point is also more likely to become a hotspot and cause preignition, this is why racers will polish the combustion chamber of a cylinder head, to get rid of any potential hot spots

I wouldn't be that concerned over the electrode becoming a hot spot. While copper has a higher specific heat and thermal conductivity than platinum or iridium, the size of the precious metal electrodes are generally going to be a lot smaller. The iridium and platinum have densities that are relatively close to each other and are almost 2.5 times more than copper, but the specific heat of copper is about 3 times more than iridium and platinum. I'd probably say the ability to shed and absorb heat in the electrodes are similar in the long run. What is important about having a smaller electrode is the near-instantaneous heat absorbtion rates (as I understand it, this is mostly a function of surface area). That is, its ability to reject the absorbtion of heat energy directly from the spark itself. Larger electrodes are going to be more prone to absorb spark heat (quenching), which can lead to misfires. By helping maintain a hotter spark, there will be less chance of misfire.

Also if anyone is considering getting an iridium plug, be sure to find one with a platinum ground electrode (I don't think any are made with an iridium ground). The CDI on modern cars actually spark twice per 2 rotations. A plug with a standard ground will cause the ground strap to wear twice as fast as on a standard plug. Especially considering one spark is generated in the opposite direction, which tends to wear the electrode faster than if it was simply on the receiving end. NGK makes a plug like this but last I checked it wasn't available here through normal distribution channels. Nissan/Infiniti may be able to get them, but they would likely cost a small fortune through the dealers.

Denso does make such a plug that is available here as well, but its not coming up as an option for the HR motor on sparkplugs.com. I am using a set of them now on the Titan. They offer no performance increase that I can sense (as I expected and Dave states), but for the additional 5 cents per plug I spent, if it can get me a little more life, then I don't see it being a bad investment.

The NGK IX iridiums look a lot nicer overall, than the Denso iridium plugs, but lack the platinum ground. I'm running a set of those on the GF's car (CRX) and motorcycle which both use conventional ignition systems.

[evildky]

does the VQ use wasted spark?

[C-Kwik]

You know, it was my assumption that all CDI systems did. But since you asked, I looked it up and now I'm not so sure. Not sure specifically with the VQ. Scartch that part of my post until someone can confirm or until I find an answer. Got a physics final tonight and a chem final tomorrow so I won't be able to dedicate any time to this until thursday.

[TITANG9]

So C-WIK, Denso Iridium would be the best choice for a G35 or 350Z(2003-06), right? I mean, with an engine N/A and few bolts on.

IKH16 or IKH20..?

[Roninmedic82]

U know what..... f*ckit, today I had some Iridiums installed(with pcv valve) and you know, my gas milage went back to 30.2mpg@78mph on cruise, my throttle seems a lil jumpier the way I like it.

most of you guys are worse than females arguing over whose vagina smells worse. although bmike had me going with that precious metal $hit.and congrats on being a bonifide h0m0...." you disgust me"(you know I'm talking too), and "huh huh...not being a prick, just being myself" being lame!
