Does the my 1999 Dodge Ram 1500 5.9L Intake Manifold need to be so big?

I'm looking for an aftermarket intake manifold, and everything I find doesn't have the plenum space that the stock one does. Is there a reason for the stock one being so big? And does it matter that the aftermarket ones aren't?
 
changing from a stock intake could make your computer do funny things because the manifold pressure changes.
