I de-snorkeled my Boxster S a couple of years ago and I thought I got a slight decrease in mid range performance - so I replaced the snorkel (but removed the bottom cup piece) and the the torque curve came back to what it had been.
If you think about it, the snorkel mouth is sitting right next to the (cool) airflow behind the louvre entrance, so this may be a help compared to air being drawn from a hot hole outboard of the filter airbox when the snorkel is removed.
So mine is now re-snorkeled.
