Where is 1999 Oldsmobile Aurora coil pack?

The 1999 Oldsmobile Aurora's coil packs are located on top of the engine, one for each cylinder. They're not a single unit like some cars; instead, there are individual coil packs for each spark plug. To be precise, they sit directly over the spark plugs, making them relatively easy to access (although you might need to remove some plastic covers for better visibility).
