I think it is a different intake manifold, not air intake or "filter", I have never seen an intake designed for only the 325/330. Everyone i have seen i think is designed for both...someone jump in if I am wrong
EDIT: just saw you were in canada, It might not be true if you have the 2.5 motor, not the 3.0, I don't know if your 325 in canada is the same spec as ours a 3.0? I think the 325's in the rest of the world really are 2.5?
