On a 3.0L MFI motor that are in the heads on the outside of the engine, pointing to like 3 and 9 o'clock on the engine. On a 3.0L DOHC engine they are inside the valve covers. On the front bank, you need to remove the coils and then the plugs, but for the back cylinder, it is easier to remove the upper intake to access and remove the coils and plugs....
