You heard correct about the Platinum plugs. They actually have a piece of platinum in them, hence the name, that heats up very quickly. What this does is help ensure a more complete burn in the combustion chamber, thus reducing wasted gas and in turn, lowering overall emissions. Platinum plugs are great for a stock daily driver, and can last a long time because the platinum gets so hot that it burns up any deposits on the plug; in essence it is self-cleaning. However, on a turbocharged or nitrous application, where you are increasing cylinder pressure and thus, heat, the platinum in the plug can become the hottest point in the combustion chamber and can actually ignite the mixture before the plug even fires. This is called pre-ignition, and actually tries to force the piston back down the cylinder while it's on it's upwards travel. This is not good. This breaks rods. I hope this helps educate you on exactly why platinum plugs are bad from a performance standpoint.
