why not to use......?

[austrian type-R]

Why is it not good to use platinum spark plugs with a supercharged engine? I?ve my stock NGK PFR7G-11 in and they seems to look fine after 10000 kilometers.

I?ve heard that copper spark plugs are better than my platinum. PLEASE, can somebody explain this to me?

BTW: What is with those Denso IRIDIUM plugs?

-copper is more conductive than platinum is.

-platinum plugs have a longer life than copper plugs.

-denzo iridiums are probably the coldest plugs on the market for our cars.
