I might buy a set of Iridium just see if I get a differance in butt dyno or gas milage. The plantinums are plated at least from what I was told if it was pure platinum they would cost a shit load. Doesn't Copper have a higher melting point than platinum?

 

I even heard about the "Silver" Spark Plugs... A lot of people is talking that this spark pugs have better mileage and power because its conductivity... :roll: :roll: :roll:


I tried the Bosh Super 4 and the Bosch Platinum+4 and both have better miles x gallon... and you feel the difference in power, because the good burning of the fuel in the engine

 

I used to run Bosch Silvers on my BMW. I remember hearing somewhere that silver is a better conductor of electricty than copper..I may be wrong but this sticks in my head for some reason.

 

I used silvers they were nice but they dont like it when you run rich.... Needless to say this was during the time I had my high flow fuel pump but the stock regulator lol.gif ..... They were good while they lasted tho. I still dont think they were as good as the Iridium ones that I have now tho.
