i blast through some very deep road rut puddles up to a foot deep and so far so good.i'd worry about the gas tank vent before the intake.
I plan on buying @Bayouownbeer 's kit with filters.
More info - I don't know where the Pioneer's filter is or how difficult it is to access. The Talon's is in the bed, so the storage box has to come out, an inconvenience at best, plus the complexity of the o-rings. The snorkel filter is 'right there', I can watch it, know when it needs cleaning, pop it off and put the spare on, all in 20 seconds; there's no guessing about its condition (and missing that guess by a mile
).
I just took apart my air intake box, and it actually has an approx. 4" cube pre-filter. It's not very dense--looks like it's designed to capture some dirt and larger debris. It has a scoop pointing backwards, and it is almost as high as the hood. Part of the box is also a cover for the fuses, so one would have to figure out an alternative for covering them. Don't know if it was like that for previous versions.
The outer filter on a Uni is quite coarse, I felt it would be pretty ineffective but when I took it off to clean the inner filter I was surprised at how little dirt had gotten through it. I'd oil that 4" cube pre-filter assuming that it's foam and not already oiled. I think that will help a lot although you'll still only have approximately 4" of exposed surface area (but 4" thick) if I'm picturing it right.
(just before its first cleaning). Lots of surface area.

That cover is also for the relays (not fuses) they will be fine with out that cover. If you r worried about the relays u can always put some dialectic grease in the connections. But honestly if u are not around much deep water areas I wouldn't worry about it, I would recommend extending the vent lines either way. Good luck!
Originally the air intake faced forward, thus allowing water into the air filter. Honda sold an aftermarket kit that allowed it to face rearward. They then redesigned it to face reward for the next model year. The actual air filter is located between the dump bed and front seat.
