2l intake on 2.4l
They seem to be quite similar and from what I've heard, alot of the 2.0L and 2.4L parts are interchangeable. I do know that the 2.0L intake manifold is rather poor flowing, get the Indy intake manifold if possible. I'll check to see if the 2.0L and 2.4L intakes are switchable.
It is a brand name. Indy Cylinder Heads Inc. makes a 2 peice high flow intake manifold that increases horsepower in a 2.0L DOHC in a Neon by 26 horsepower at the wheels. I'll give you a link to it in a sec. Here you go:

All the pictures I have seen looks like the manifold would bolt up the same just different holes are used, and I think that the angle of the intake has a bit more of a curve to compensate for the angle that the 2.4L sits.
