If you ask the manufactures, they say the platinums are better but they also say there is no proformance advantage when there is a before and after.

Platinums are good replacement when getting to the plugs are really hard to get to, like in Magnas.

Another thing, fouling a platinum costs @$20 each, fouling a Copper @$3 each

platinum are good as long as you are not boosting to hard or working you engine hard. I had them in my car they are good no difference in power but they last 100,000km which is good that means you only ever have to change them never. I had to take them out though when my new turbo and started running the car on 16psi as the platinum on the plugs melt and fall into were it is not ment to be NOT good. so if just running the car normal i would put them in, but if you are running a lot of boost just the cheapos is better. If you want i have a set of platinums at home that have done about 1500kms you can have them for good price as they are no good to me anymore sent us a pm if you are interested

I run 20psi through mine & my platinums are fine, maybe it comes back to tune??

Try iridiums, the melting point on iridiums is like double that of platinums.
