The purpose of the plug is to ignite the fuel.  In some circumstances, 
different materials are more or less prone to oxidation in heated 
environments, so yes, in theory, different plugs might make a difference. 
 Also, plugs come in temperature ranges, different gap settings, different 
insulator materials.  I've honestly never figured out technically the 
reasons why, but if someone on the list can explain why a plug is not a 
plug, I'm all ears :)
