Waht does this do, and would there be any advantage in removing/blocking it off? Naturally, none of the aftermarket intake tubes have this obscene-looking thingy.

Thumbs up

It serves to straighten incoming airflow. I'm currently having a mental block & I can't remember what it's called, but it's a good thing to retain .

In the world of NVH, it is called the Helmholtz resonator.
It is an enclosed resonator or hollow object designed to resonate at a particular frequency.
occaisionally used to "tune" a recording studio or concert hall by reducing the space's resonance in that particular frequency range.
It may be referred to as a "bass trap" in music studios as Helmholtz resonators are often used to reduce bass or low frequency resonances.

Thus, the MAF non-blowage, and mandatory keepage. Thanks, all.

PS-Tom's turbo RS is a killer.

Hmmmm... And all this time I thought it was just a handle to help you hold the intake piping out of the way when changing your filter. ehhe!

No, you will not blow your MAF sensor without the Helmholtz resonator. It is there purely for noise purposes only. My company (Roush Anatrol) has build many many of these resonators for automotive intake systems.
People blow their MAF sensors because they hard mount the sensors to the chassis after an intake mod.
