Desnorkle clarification

[fragdude]

The two things I've heard are that its for both keeping the noise down, apparently porsche decided that it was easier to have all their cars meet the strictest noise restrictions (I believe Sweden was the country in question?) and to keep foreign objects, such as cigarette butts, out of the intake.

Althought I have seen this on other forums:

I read that the 03-04 model have redesigned snorkel... I guess there's no point to remove mine is there?

I also read that it acts as a device to grab cold air as suppose to hot hair right outside the rear fender.
