The baffle’s function is misunderstood; it is there so that the car meets the ridiculously stringent Swiss noise laws, the same reason for the overly complex Sports Exhausts design, with its valves and speed controls as a factory installation. The Swiss have very tight requirements on how much noise a car can make and certain speeds and under certain conditions; the so-called “snorkel” is there to comply with that requirement. It’s rather peculiar design speaks to meeting the sound level without disturbing the flow of the rest of the intake system, which obviously works. When it is removed, the sound level rises, but the intake system is no longer “optimized”, so performance suffers slightly.
It would be interesting to see if gains could be made by totally redesigning the runner system to operate without the baffle, but that would require a lot of flow bench time at a minimum……………..
