ACDELCO Coil pack & ignition module preference questions

[dwall]

I need to replace a known good pair and return them. It seems best choice is 'Made in USA' ACDelco parts. D1996 module and D552 coil pack from Highway Stars are a likely buy:

Results for coil

1. Are these ACdelco part numbers always 'USA' made?
2. Are the D1996 & D552 the same as the Magnovox parts I read about somewhere?
3. Nos4GN sells a HIGH Performance version of the coil pack for an upcharge - is it worth the extra $ ... and why would it be better? Coil Pack - Premium High-Output
4. Nos4GN also has 1 year warrantee - how often do coils & modules fail within a year vs. arrive DOA (or fail within a month) for example? For me the replacements will get limited use til next spring.

An old inquiring mind wants to know.
