   My experience with Bosch Platinums over the years has been less than   
   satisfactory. Lots of compression seal problems and resulting   
   misfires.   
      
    NipponDenso Platinums are the Cat's Ass for Toyotas. NGK Plats are   
   pretty good too. Dual Plat is only "required" for waste spark systems   
   (double ended coils), which Toyota has pretty well gotten away from   
   (if not totally)   
      
   I put Iridiums in my Chrysler PT Cruiser - and a couple months later I   
   developed a #1 misfire at idle.. I ruled out plug wires and coils by   
   switching them, and figured I'd switch plugs between #1 and #4 to see   
   if the misfire followed the plug.   
      
   Misfire went away.   
      
   It appears ONE of the plugs wasn't happy firing "backwards".   
      
   That's the only experience I've had with Iridium or "fine wire" plugs   
   in the last 20 odd years.
