My '00 300m has a largish air intake box mounted over the battery (where the air filter is located) and a large 3" diameter corragated rubber hose running from this box to the engine manifold. But mid-way along this large hose is a smaller 1 or 1.5" side port that is connected to a smaller, irregularly-shaped plastic box - same color and type of construction as the air-intake box.
There are no ports or any sort of connections to this smaller box, and
it looks molded in one piece (so I can't take it apart).
I can't figure out what the purpose of this box is, unless it's for some
sort of esoteric function like impedance matching or resonance damping.
