Careful with the platinum plugs, they may affect idle. From http://64.105.196.250/Reviews/iridium.htm :

"There are three basic concerns when shopping for a spark plug, idle quality, performance, and longevity. From what I have found, copper seems to idle the best as well as offer the best starts. The downside is copper plugs show gap erosion at around 7,000 miles. While platinum plugs last well beyond 7,000 miles, they do not perform as well as copper. This is where Denso enters the picture. Denso claims good all around performance as well as longevity with their iridium plugs. Start up and idle is at least as good as with copper plugs, and better than platinum plugs. Longevity has yet to be determined."

Trouble is, the Denso plugs are about $12 each.

I put a set on my wife's S80 2.9, and they run fine, both idle and high speed. (Probably overkill for the NA engine, but what the heck.)

Good luck.
