Does the VX have a cabin filter?

Now, before you start hatin' on me and throwing out one word answers, let me explain:

*Mom's Buick spews the smell of armadillo bung every time the car is turned on.
*I located the "air inlet" under the hood, and there's a big, horribly dirty and disgusting cabin filter shoved in there (bigger than the stock VX engine air filter).
*Went back and read the owners manual and it isn't mentioned anywhere.
*Auto Zone can't even order the filter, The Filter House just shrugged their shoulders, and the Buick dealer had one in stock, but Chester the Dillweed behind the counter didn't know a thing about them...

So, I found out that the Buick has a cabin filter so secret that it's developers were killed upon completion of the project.

At the VX only run in Moab, I was following Todd down a red dirt road at about 50 MPH, and the red dirt was shooting through my vents like the onset of a biblical plague (Hollywood style), so I'm guessing that we have no filter in the VX.

Has anyone fabbed one?
Any ideas?
