While i would still get one because its cool AF, i don't think any snorkel I've seen is providing enough air for the 5.7 at WOT.
If i ever Supercharged, it would have to go as well. I also wouldn't put my LX in that deep of water where my interior or submerged electronics would be trashed.
That being said I also think they are far better for dust than water and is a solid use case for them.
That being said, that monster snorkel is by far the best looking design IMO. By a long shot.
It also looks the most flush and aerodynamic thus less noisy.
