I believe the general consesus is that the platinum plugs actually offer less performance over the normal Bosch coppers - basically, use what the factory used.

There's also stories of the electrodes burning off on turbos and getting hammered around in the combustion chamber. Stick with NGK or Bosch coppers in the heat range you prefer, I use NGK in one number colder and run a tighter gap.

I stick with copper in all of my cars. Never noticed ANY difference. Save your money for something that will make a difference. On the other hand, if it makes you think the car runs better then maybe it is money well spent.

I did it, switched back after I was stranded, My wrench suggested I use copper's. according to him, The plats will cause problems with the coil. (Exactly what happened to me)

I use coppers in my 944 spec car. One track day I swapped from +4's to coppers. Down a couple longer straights I seemed to by making few more revs with coppers. I have stuck with them every since.
