Spark Plug for 2004 Prius

I was gathering parts for my 110K service.
Decided to do the plugs at 110K miles.

Went to order the parts at the dealer. (wanted to get OEM parts)
Ordered them.. said they would be in today..

The parts guy called.. saying he had to call toyota.. because the part number he ordered from toyota.. came back as an invalid part number.
When he called toyota.. toyota said that it is the same as in a 2003 prius..

I said OK.. do you have those.. and he does..

I was under the impression that there was a change from 2003 to the new 2004.. with the plugs..

But.. I could be wrong..
Can anyone confirm this for me..

I am suppose to go pick up the part at 3:00 PM eastern time today..

Thanks,
Scott
