PRB Intake Manifolds

I was wondering if the 02-04 prb intake manifold is the same manifold as the ep3 si prb intake manifold/ 05-06 rsx type s prb intake manifold? I know they have slightly different part numbers but didn't know if that might just be a cataloging thing. I have looked through many threads and done many google searches and can not seem to find any info on the matter, everyone is too concerned about going to rbc manifolds. Thanks for your help
