bosch platinums run wayyy to hot for the 3.1 / 3.3 /3.4. They may run ok in your quad 4, but I wouldn't reccomend them to anyone with a 60 degree V6. If I were you Deb, like Herb said, I'd use AC Delco's. You only really need different spark plugs if you need to run them cooler for boost, forced induction, ect. But on a mainly stock naturally aspirated engine, I would just stick with the stock plugs.
