Spark Plugs and Wires

At what intervals does Pontiac suggest you change the spark plugs and wires in an 2005 Sunfire?

The Haynes manual says that the wires should be inspected and changed, if necessary, every 30,000 miles or 24 months, whichever comes first.

Plugs (platinum tipped) should be changed every 100,000 miles or 5 years, whichever comes first.
