Air follows the same general rules lol. Let me explain:
First, the engine needs a volume of air right? How it gets this volume is the key. If we only had a 1/4" line 100' long supplying air to the engine it would have to suck like a, well it would really have to suck hard. Conversely if it had a 6" pipe a foot long it would be easy! With this you are increasing the length and adding some bends. To keep velocity the same and not make it suck harder you increase diameter. Small pipe and high cfm equals high velocity. Bigger pipe and high cfm equals lower velocity. Now if we could only find a way to force air in there...
don't forget though that in motion the snorkel acts as a ram and there is plenty of air to go around
