Probably not as helpful on an FI setup as NA as the dynamics of air being forced into an engine are different than when being drawn into an engine. I'm not an expert so don't ask me to elaborate: this is just what I remember from physics class and reading about motors.

Aftermarket intakes might be useful in the area where these blocks shine. Testing seems to be indicating that the factory intake becomes a limiting factor at high rpms. Even if the intake you select does not cheat the MAF sensor, if you have made mods that are moving more air at high rpms, a less restrictive intake should allow those mods to move even more air.
FI systems do away with the factory intake for two reasons;
1) It's big and in the way.
2) It's at its limit and FI needs access to a lot of air.
It's a decent system, but it was designed for an engine that was set up a certain way. It looks to be just enough to handle the factory engine. Once you start making other changes, you need to look at changing the intake too.
At least that's what I get from all the reading I've done.
Just changing the intake all by itself won't accomplish much, but changing it as a supporting mod for other mods makes sense.
EDIT: As Crawford pointed out further along, there is a third (probably #1) reason.
3) MAF sensor scaling on the stock intake is insufficient for a serious FI system.
