Coil Pack Identification

[Chris03]

Hi all, new here.
I was wondering how to identify what year a coil pack is based on its number.
I have an 03 LS V8. 7 coils have the number: 2W4E-12A366-BB the last has a suffix of BE.
I know the suffix is the engineering revision, but, can't find anything on the internet.
Any help would be appreciated.
I was thinking on getting Motorcraft coils from Rock Auto, number: 2W4Z-12029-BD.
Any thoughts on those?
Same number comes up on Amazon for $13.90, Rock Auto is $47.79....
Help....
TIA.

I think those are the latest versions of the coils.

Amazon has a lot of fake and/or misrepresented coils. Rockauto will likely be your cheapest bet.

Because of the great posts on this site i was able to diagnose a problem with cylinder 3 COP and take my '05 into the dealer for a warranty fix. Two COP's and two plugs under warranty, two plugs I paid for so the passenger side is all set, total cost $70.99. Hard to argue with. Cheers, gm.

PS-The dealer's retail on the COP's was $77 each.
