I would just put a couple of words regarding my experience with the plugs. For over a year, I left my 2nd gen at pretty much stock boost, about 11psi max. I had the denso iridiums in it and it was fine. When I later turned up boost to 15-16psi, I noticed on long trips @900 plus miles that the car begins to hesistate or buck intermittently whenever I tried to boost. I changed the plugs to NGK copper and have tried the platinum and the problem dissappeared. I thought it was a fluke and went back to iridiums and the problem returned. So I replaced the plugs with platinum again and it dissappeared. This has been my experience. I don't know if anyone else had the same problem. But I think sharing these experiences will help the community gather info and hopefully guide others.
