keep in mind, in regards to drainage, unless you get one of those mushroom style snorkels all snorkels have the same basic exterior design. drainage shouldn't be a worry, when it comes to a snorkel. the amount of rain, that will actually get sucked into your snorkel is negligible and you shouldn't be in a creek deep enough that the snorkel intake is under the water line!
yes, water, oil, coolant, anything in a fluid form versus vapor form will lock up a motor. anything in a vapor form will not. every crankcase ventilation system operates under that principle, in that cylinder head and crankcase vapors are directed into the intake manifold to be re-burned.
another thing to keep in mind, boosted turbo and blower applications use water misting systems to cool combustion chamber temps. we work with a handful of bmw and porsche tuners that can give you all the information you need on the benefits of water misting.
the difference between the southdown snorkel, in regards to the D2, is the deletion of the fiber mesh connector to the air box. with that being said, if you really think about it, if your snorkel connects to the fiber mesh air-box connector, you just spent at least $400 on something that does not actually work properly.
almost every D2's mesh connector, we see at our shop, has holes in it....and 100% of them are street driven vehicles. most jag's have the similar issue.
