Ive got the bosch platinums, 5k miles and no problems thus far.
I should hope so, cause the OEM plugs are intended to run for 105,000 miles, although I'll prolly change mine when I reach about 40-50k miles or so when ever that is.

There is no such thing as Iridium/platinum plugs. It's one or the other.
The NGK 7746 (IFR7G-11KS) is the plug that the NGK catalog calls for in '03 S2000's. It is an iridium center electrode with a platinum side electrode.

Laser Iridium spark plugs provide superior ignitability and long service life. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions

Laser welded Iridium center electrode tip
Platinum disc welded to backside of ground electrode provides
long service life
