I installed new factory plugs in my car, and it turns out the previous owner installed Denso Iridium Power Plugs. The car ran fine with these, I just prefer the factory platinum plugs.
$20 shipped, compared to around $10/ea new.
The plugs read Denso Iridum Power IK20, they're the denso performance PN for all years of NSX, 1991-2005.
