where are they located?

[carte22]

I have a 2003 Chevy TrailBlazer.
76,000 miles
4.2 L V-6

We want to replace the spark plugs ourselves, to save a little money, and this may be a dumb question, but where are they located? We have change plugs before, but on older [COLOR=green! important][COLOR=green! important]model [COLOR=green! important]vehicles[/color][/color][/color]. Could you help us out?? Thanks!!

they are in the middle of the engine on top of the valve cover.under the coil paks. The plugs are platinum and should not be replaced until 100k. Do not ever use bosch platinum ever ever
