Default When did Lexus start putting in Iridium Spark Plugs

I have a 94 SC300 and was wondering when Lexus started putting in the Iridium Spark Plugs.

If my car doesn't have it now (I doubt it but I may be wrong), I would like to put them in at the next scheduled spark plug replacement service.

Thanks!

I believe Lexus started to put the IR spurk plugs in 98, but my info is only for V8s. I don't know if they ever put the IR plugs in I6 or V6.
