| If your car is perfectly in tune, and you use the right gas, then you're just wasting time and money. Spark plugs themselves do not create heat, they dissipate heat from the combustion chamber; whoever told you otherwise is just plain wrong. Copper and platinum plugs in the same heat range dissipate the same amount of heat, and platinum is no hotter than copper. [ http://www.ngksparkplugs.com/techinfo/spark_plugs/faq/faqheatrange.asp?nav=31200&country=US ] Furthermore the electrode itself does not decide the temperature range of the plug; the insulator nose length, the gas volume around the insulator nose, and the materials/construction of the center electrode and porcelain insulator decide the heat range. Thus for each type of electrode material, NGK constructs the rest of the plug around it and the preferred heat range to make copper and platinum heat ranges functionally equivalent. If the platinums in your heat range were burning too hot (> 850°C), the electrode would begin to melt and the ceramic insulator would also begin to degrade.
