Spark plugs?

stumpjumper · 07-03-2006, 12:25 AM

Iridium is an element. It is here because the meteor that was said to have killed the dinosaur's was made of iridium. It formed the gulf of mexico a few million years ago. There is a layer of iridium about an inch or less covering the earth that was caused by that meteor. Probably the best metal that exists on the planet. Probably not the best metal for spark plugs though. Stick with NGK. They are the best bang for the buck. All it is, like most already said, is the electric signal traveling through the least resistance. The gap provides just enough for the electricity to travel through the free space to reach the other metal to continue the charge. But, so much energy is lost in the gap that the charge is basically done when it reaches the other electrode so the charge ends at the gap. All you need is one electrode, one with good conduction, which ngk provides. Spark plugs don't do much besides conduct electricity. Clean plugs, gapped correctly are fine. Worry more about air and fuel flow, that is where the power gain is at. I believe the injectors are capable of a lot more flow then stock; get a chip to balance air and fuel flow to get the best power. Change plugs about every 15K and you'll be fine.

and i'm out.

LOL, and now a word from the resident geologist...hahaha

first of all...we were talking about NGK Iridium plugs, secondly changing plugs every 15k on a good running engine is a waste of money. and thirdly no one was debating the fact that adding fuel/air, etc yields more power...the discussion was about spark plugs and which ones are better...but I see that some people just want to steer the topic elsewhere so.....

I can feel the love.

I wish I could, but nothing will happen without $$$

Agreed, Money is the limiting factor. Haha. So if there is only so much iridium...in a few thousand years of making spark plugs wont some orignal NGK iridium plugs from now sell on ebay for like 2 million? im gona get some now and hold on to em. To add to the post...I still say...whatever works use it. He is right on one thing, spark plugs just need to conduct electricity. Longevity is the main thing i would look at, As long as they are doing there ignition job correctly.
