Iridium's are supposed to last 100-120k. Platinums supposed to last 60k but are cheaper than iridium. Iridium also tend to have the fine tip on their electrodes.
nuthing man exactly the same they just last alott longer so you'll only need to change them like after 100,000 km
only good if u have a FWD V6 type car where the back 3 cylinders are harder to change if you know what i mean
on a 4 cylinder i'd rather use the normal copper core ones :D
they both last 100k if they are the laser platinum or laser iridium because the tip and the ground has the special metals
if its only on the tip they last till bout 50k or so
since you drive a honda.. just go for copper plugs since they can be changed in 15 minutes
This is correct.Quote:

The standard s2k plugs are pfr7g-11s which are laser platinums. So i would just buy these plugs

My H22A NGK Iridium IX plugs have lasted 100,000km...According to the bonnet sticker or the service manual, the Prelude comes with Laser Platinum plugs from the factory and they should last 100,000km too?
Ahaha thank guys! They don't come with copper.
correct but why pay so much?Quote:

I don't really recommend this, but you could also get a cheap socket set with a spark plug attachment for under $30 too.
i was under the understanding that iridium burns fuel alot faster/hotter than copper?Quote:

shop smart and you can have a good spark AND at a good price.
i'm no expert on the material properties so i'm not going to comment
$10's not bad!
yeah.... i bought some for the camry, and also same price. even better when i bought them whilst i was there, and no need to pay for shipping, just throw them in my carry on.
the security guys was like "i see metal, open your bags please!"
*hands him my packet of spark plugs* and he gives them right back after finding out they are spark plugs.
I think you mean it warm you car alot faster at start up.Quote:

i can only see that being a good thing i guess. happy to be corrected if its wrong
Mine cost 80 total back then including fitting.Quote:

Ie. by changing copper plugs more frequently what are the benefits?
Like I said I've done 100,000km since I replaced the plugs nearly 4 years ago. I've never had to worry about them. How the tips currently look, I don't know, but my engine has never misfired/missed a beat.
Ill try using them until I reach the 110,000km mark.....which is another 8000km :)
if my highschool science knowledge still holds up...Quote:

so as far as lightening a fire with electricity... copper would be best. however copper if I remember correctly is a much more volatile metal compared to iridium and platinum, so it's way more suspectable to corrosion/carbon buildup etc etc etc.
yea but just use copper ones if you want better spark i'd use the iridium and platinum on FWD V6 cars that take too long to change the rear 3 spark plugs lolQuote:

ive currently gone down the iridium route for all my cars, even on a daily camry that my dad uses.
IMO yes, i'd never bother unless i drove a subaru
lo yes or a subaru hehehQuote:

how's a legnum spark plug arrangement like?
3 facing the radiatorQuote:

oh.
FML.
thanks for that. no i havent seen a copper spark plug before, let alone one running on E10.Quote:

Yes like i said, but you'll need to change and check it more frequently.Quote:

It's because if you are running a rich fuel mixture because of high boost pressure, then the plugs could foul quicker. Higher combustion temperatures also cause the electrode to wear quicker. So it makes sense to change it more often for less dollars.Quote:
