Box in intake track?

[Back-n-Black]

I do not have a picture handy, but what is the little square box in the intake track for a 03 libby gasser? I see with a lot of CAI kits this is eliminated without any problems. What is the purpose of this box? Improve low end tourqe? Help idle?


Found one. Tthis box on the right with the 3.7l stamped on it.

Thanks in advance.

I'm not sure what the purpose is. I do know there are two breather tubes coming off the back side if it for crankcase ventilation.

Our '06 does not have the box, and the PCV routing is different.

But then again, I read somewhere that the '05+ have a different cam, torque converter, ect.

Maybe it's there for a reason. I don't know.

Its an airflow resonator box.... basically it helps cut down on the "rice intake sucking sound" that you might hear without it.... it jsut swirls the airflow around and makes it a bit more turbulent than a straight through pipe...

old thread i know, but does it have to be removed when installing a cold air intake? IMO i like the loud intake sound

Yes, it gets removed so there is room for the cone type air filter element as
well as the heat shield thingy that usually seals against the bottom of the
hood.

It doesn't get removed with the K&N Cold air intake (obviously as the picture above has it and the K&N cold air intake...)
