I know its been talked about and probably said before but I'm going to say it again. And yes, I did a search but couldn't really find a straight forward answer. Allright, here it goes:
As I read throughout the forums, I've notice more people are trying to encourage getting a "ram air" or a cone filter as oppose to a cold air intake. I basically want to know why. To me, it seems to make more sense to get a CAI than ram air since your getting true cold air. I know that even if you have a heat shield, you're still getting the engine's bay air while a CAI is sucking in the cool air from outside. The only setback I see for having a true CAI is if your car hits a puddle or get submerged you're pretty screwed. But seriously, I don't exactly think that any BMW owner would ever do such a thing with or without a CAI. So why do some of you bimmer owners get it?
One last thing, are the HP gains any different for ram or true cold air intake for a BMW.

Booyashaka!!!

how the hell is a dyno test going to give you accurate results if u have a CAI? you are not moving, so how is the extra air getting in to create preformence?

That's what I was wondering, how could you dyno it? The car is stationary! So wouldn't it make more sense that ram air produce more power since cooler air is blowing into it?
