Did anyone ever find any data showing that this increases performance? As far as I can tell, the only difference is that you have a crappy Fox style throttle body which is more likely to stick on you.

I have yet to see hard data showing positive power gains with a NA
application

I know some like how it looks as opposed to the OEM SN setup
but
That is a whole nuther kettel of fish

I've seen several say pa applications do gain from this mod

The stock lower intake is the single most restrictive part on the 5.0. You will see a power increase of 10-15hp but like everyone else says the heads will be the next big choke point. It will not be huge and you may barely even notice it but I could not notice any power increase in my car when I done a O/R x pipe on my car either.

I would go ahead and install it but I have had my intake off a few times and I can get it off in about 20-30 minutes.
