Oem plugs?

I have recently got myself a Sienna and I'm unsure how old the spark plugs are. It has 150000 miles on it and before I embark on getting those back 3 plugs out I just thought I would ask what brand the original plugs were from the factory. The ones that are in now are NGK iridium.

Our 09 has 135,000klm's on it (approx 75,000miles) and wondering at what point the plugs should be replaced? The 09 is using more fuel than our 04 3.3 but runs good.
