I've got the EVO and paid $125 for a new one off of EBay, the Outerwear prevents any water ingestion. I think of it this way, with the RPM's these engines rev at and my engine displacing 3.2 liters the amount of air flow is substantial. If I was running a marathon suckin' air through a straw and then spit it out and breathed on my own I would feel a whole lot better. I'm sure the intake on the Boxster was mandated by the U.S. backed EPA. If Porsche had there way the intake would be allot less restrictive than it is. So I took it upon myself to free it up.
The sound is great!
