Im curious if there are any numbers on the Bosch coil packs that will help me identify its manufacture date or age of the it.

Manufacture date is printed on the body of the coil pack, below the part numbers, in YY-MM-DD format

If you're unsure or just buying the car, it's not a bad idea to just do a fresh set of plugs and coils as preventative maintenance. I did it when I first got mine, that way you get the peace of mind and can establish the intervals that you'll change them out. Car will run smoother and honestly, the N54 eats them up so you'd have to do it soon regardless.
