Here. Just read this.
The age old question of whether or not a spark plug can really increase the performance and economy of a vehicle has raged on for years. While in general the basic consensus is no, to be quite honest there is definitely sufficient evidence out there today that not all spark plugs are created equal.
There are spark plugs that do seem to increase the efficiency of a vehicles engine on occasion, and there are certainly spark plugs that last a lot longer than others, which besides saving you additional tune-up costs, leaves just a few less old spark plugs in the landfill somewhere.
Which Spark Plug Composition Should You choose?
Copper
The basic spark plug is made of copper, which is actually a pretty good conductor of voltage. The problem with copper is that it is not as hard as some metals and it therefore wears down with the high pressure and heat inside the engine. This wear eventually causes the plugs to foul and work less efficiently over time.
The wear also can cause the air gap in the plug to increase, which can cause a loss in vehicle fuel efficiency and even misfiring in extreme cases. This is because it takes more and more voltage to jump between the electrodes the greater the air gaps widens. One way around this is to use a harder metal, like platinum.
Platinum
Platinum is a much harder metal than copper and has a much higher melting point. This gives platinum the advantage of lasting longer than conventional coper plugs. Besides longevity, platinum plugs in themselves do not make the spark better, or more efficient than copper in any way.
The main advantage of platinum over copper is its ability to heat better, which subsequently burns off deposits better, and its ability to handle high heat, also enables the plug to hold up better and reduce the amount of air gap change over time.
The only way that a platinum plug could be considered any better at creating fuel efficiency for an engine, is if it can reduce the size of the center electrode to the size of a fine wire tip. This reduces the chance of quenching, because it leaves less area for the heat to be reabsorbed by the plug.
His design also gives the added benefit of needing less voltage to jump the gap in order to create a complete burn. This can be an particularly nice benefit for older engines with less efficient ignition systems. Both benefits give the combustion process the potential to create a more complete burn and therefore greater fuel efficiency.
Iridium
Iridium is said to be six times harder and eight times stronger than platinum. This means that spark plugs can have even finer electrodes than ever before and still have excellent wear characteristics. Platinum is precious enough, but iridium is even more precious, which is why it is hard to find a single platinum plug for much under $6-$8 and an iridium plug for under $12-$14.
Is it worth the extra cost for platinum and iridium? Yes and no.
If you are willing to change your plugs once every year or two depending on your driving habits (and it is actually quite easy to change your spark plugs), copper plugs can offer good performance and efficiency. It is also worth mentioning, that with platinum and iridium plugs you generally get what you pay for.
The more expensive the plug, the more platinum (double/triple coated) or iridium is usually used in the plug. A thin coating of these precious metals will not fair as well as a thicker, so in general, you won't want to go the cheap route, as it would be better to just use good old copper for your maximum value.
However, in general, the standard copper plug does not reduce quenching like many of the platinum and iridium plugs can. With this said, technology has opened copper type plugs to the similar benefits of the fine electrode using various configurations and shapes. This is where the specialty plug comes in, such as the U-groove or Splitfire.
There is much controversy over the benefits of such designs, but we will cover the most popular ones as well as discuss their potential and ability to perform as they have claimed in part 2 of this series.

Did I say E3's hmm maybe not. Take a look at this...

Not all plugs are created equal as they say and as I Ride stated, the copper plugs don't last as long. You'd end up swappin' those puppies out every 10K compared to premium plug.

I rock the $.99 chapions in my dakota and other than its time to change them (im like 28k mi on them) they have performed great. I just want GOOD quality for my dak and my girls neon. My BMW will get the high end performance plugs.
On a stock motor or a motor with simple bolt ons, like my dak, a good copper plug would be fine. On a boosted motor or a built NA motor I would use a high end performance plug.
Just my $.02 and a second thanks for the wealth of info. This post has helped with all 3 of my cars

ok guys i got some questions i want plugs for my neon but what heat range can i go can i go and 8? and can i use a none projected electrode or do i have to use a projected one? here are the 2 plugs im contgaplating using and i can get then in a 7 8 9 10 heat range and the electerode i can get projected or not here are the two web pages wit hthe plugs
http://www.ngk.com/more_info.asp?AAIA=&pid=15057 that is the projected plug
http://www.ngk.com/more_info.asp?AAIA=&pid=3419 this is the none projected plug withc i was going to use
http://www.ngk.com/more_info.asp?AAIA=&pid=16894 this is the racing plugs i was deffently guna get a set and use tehm when i use nitrous with my turbo.
if you are realy looking to be safe when etreme condtions happen like nitrous and turbo you could use this plug but i dont no if you loose power with this plug
http://www.ngk.com/results_cross.asp?pid=r58839
tell me witch of the first 2 plugs i should use. and tel me whaT YOU GUYSa think about that cool racing plug. it reduces quech and also alows better flow because the gas air mix isnt hiting the tip and ground strap because it is small. this is one reson why i wanted to use the none projected electrode. for that main reason please reply guys id apreaciate it
