Re: Spark Plugs Iridium LFR5AIX-11 1.1


Brett,
It's just that I see a lot of people rave about them in performance and power gain but you would be better off getting better coil packs and better insulated leads as your artical even states that it is a long life thing only

Dave,
Read NGK's explaination on Iridium plugs ]here

It all comes down to kV/sqmm and ignitability.
The Iridium plugs have a smaller tip so with the same kV there is a higher spark which means better ignition of fuel/air mix and better total combustion.

Dave,

I wouldn't be doing dyno tests or advocating that fitting the iridium plugs will be the answer to cheap power gains and lots of it. This is simply not the case. The reasons explained by Kev and which are included in the NGK overview are pretty much spot on.

Fitting iridium plugs will prolong the service life of these plugs and provide better ignition, since that is directly related to better combustion, it will have benefits (even slight) on performance.

So if you don't maintain you car well Iridium is the answer but if you do change your spark plugs at the 30000k's intervals your laughing as Ive never had a plug wear even at the service intervals of 40000k's unless there has been an underlying issue which you wouldnt pick up with iridium due to it capabilities to handle race track conditions

Re: Spark Plugs Iridium LFR5AIX-11 1.1


Dave,

It's you choice of course, but personally, I prefer to have better ignition and plugs which I don't have to worry about for 65,000kms at least. If you calculate that, that's 2 sets of standard ones and possibly a dead battery sooner than needed.

P.S. My battery is 4.5 years old now and it's still showing [sign in to see URL] (touch wood) emoticon

For the little difference in price between the standard and iridium NGK plugs, I know what I'll choose.

Re: Spark Plugs Iridium LFR5AIX-11 1.1


Jalal,
I ran champion gold plugs in my bluebird for nearly six years changing them every 40 to 50 thousand k's and never had to replace my battery in that time so I'm not sure where your'e going with that.
You will only have better ignition with Iridium if you keep you standard $4ea plugs in for say 60-70 thousand k's but in saying that I've taken out plugs after 80,000 k's just because I thought I should change them and they have not been worn but heat damaged only by this I mean gap has opened .1 of a mil. Its a know fact that the reason Iridiunm plugs were produced was to keep the vehicle in tune for the 100,000km waranty period.
This is all I wanted to do in questioning the Iridium spark splugs is
to work out what is the best plug for our aplication and healthy discussion gets you there quicker. There are silver plugs out there called Nology and they claim they have the best spark plug in the world but they can claim and write any data they want on the plugs as can Bosch NGK and Champion food for thought
 ]Nology

No worries Dave and like I said, it is your choice and if you're happy with the standard ones and they do the job just fine, keep using them. It is the same principal as using 95 or 98 octane fuel and try to use the very best with my exy and I don't think that the little extra per plug price justifies me using standard if I can get better ones (iridium).

Now, have you heard something we haven't which you're trying to share with us about the use of iridium plugs?

Jalal,
Not at all they are a good general purpose spark plug designed for a purpose, for car manufacturers to extend service intervals with a constant spark for its 60,000km or 100,000km life. I just thought as a forum we would have heard of other alternatives instead of just the one plug. I have no doubt I could go out and buy KLG plugs at $[sign in to see URL] ea and change them at 40,000km and not have an issue at all for the life of the Exy

Dave,

Our forum has no vested interested in pushing one brand of plugs over the other, it is just the fact that the xtrail in Japan uses the NGK Iridium plugs as standard while we here in Australia get the exy with the standard NGK ones. That is why you see the NGK iridium plugs is a very popular option for the exy and Sentras not to mention the fact that many other cars use the NGKs too.

You're absolutely free to use any brand you like and there is nothing stopping you from sharing other brands on this forum either.

You seem to have some strange way of mentioning a new brand to the forum and have to do a full circle before finally saying what you had in mind when you first made a post in this thread. emoticon

It could have been said as simple as "you guys decided to use NGK iridiums, but I decided to use Nology" Hey presto!

Jalal,
You have lost the plot. I have not fitted any spark plugs as yet and I'm asking if anyone has come across a another brand or wants to give some input into the subject so I can make an informed choice as I'm guessing that I'm not the be all and end all expert on spark plugs but amongst us we could have such an expert. I'm dumbfounded as to how you have attacked my writtings so what I don't agree with you live with it
