Performance Ignition question MSD 4.0L

Any real gains in replacing the stock with an MSD 6A box and performance plugs like Autolite XP iridiums with a MSD coil? My YJ could use some plugs and was wondering about this upgrade, I allready have the 6A.

This is helpful.

No one has this upgrade?

I will try this mod and report back any gains I get, just hope the MSD 6A still works since I have had it a while, stored in it's box in the garage.
