Desnorkel vs Cold Air Intake

[maytag]

y'al are awesome. Thanks for all the replies. ALL of them!
So here's where I should clarify some things:
It's not that I'm not interested in power... I am. This is why I'm interested in any REAL power losses that have been experienced. JFP's reasoning is very sound, but the practical application of theory is not always noticeable. That's why I was looking for something quantifiable, or even an "I installed xyz and felt a noticeable seat-of-the-pants drop...." sort of anecdotal evidence.

What I'm finding is that y'all don't seem to trust the ability of the aftermarket setups to insulate / isolate the warm air from the intake. It makes sense, of course. Though I have a setup like it on another vehicle which is actually QUITE effective, and seals tightly against the hood. But that's a front-engine V8.... very differnt situation. If the setup can't keep warm air out of the intake, then it's a step backwards. If it can't insulate the engine sound from the intake sound, then it's even a step backwards in sound, (for my tastes).

But maybe the hyperbole can that JFP described in his post is a place I can start, as well as replacing the filter with a less-restrictive one.

I am not a newcomer to making power, or modifying vehicles, or racing them. I Am a newb when it comes to Porsches, and mid-engine cars in general. So I'm approaching this as being interested in learning what y'all know. No sense reinventing a wheel that's already going. That's much better than me coming in and acting like I know everything, right? BUT: I'd like to understand it and weigh it against the knowledge I've already got under my belt. I'm not a guy who'll ever just buy and install a product (or worse yet: leave one intact) just because somebody else says I should. That'll ALWAYS be followed-up with a "WHY?"

And to be clear: I"m a smart-ass at heart. I like it when someone sends me a reply like the on below by cb350 (or whatever) because I can put on my smart-ass hat, and not feel bad. :-) I also assume others are not mean.... so no harm where none's taken, right?
