Depends on the setup. If you're wanting to make the most power out of the combo and plan on carrying high RPMs it wouldn't be a bad idea to upgrade.

Coils do wear out over time. Depending on the coil brand and model it will have a certain number of turns in it. The more turns the higher the output.

I ran a MSD 6AL box with MSD 8 mm wires on my old stock 350 TPI. I'm running the same setup now on my 383 but I added an MSD distributor and a Blaster coil instead of the MSD GM Dual connector coil.

The thing about aftermarket ignition boxes they're suppose to provide a stronger spark and sometimes even a multiple spark for a better burn. You can also get nifty other features like rev limiters, timing adjustments, and etc.

Pretty old article but this will at least give you an idea of ignition boxes.
