Where are the spark plugs on a 2000 Oldsmobile intrigue 3.5 liter?

The spark plugs on a 2000 Oldsmobile Intrigue 3.5L V6 are located on the top of the engine, between the valve covers. You'll need to remove the plastic engine cover to access them. They're fairly straightforward to reach once the cover is off, but be mindful of the potential for burns from the engine's heat.
