Best deep water protection short of installing snorkel?

You're not going to get water in the intake until you're in very deep water since the intake is up near the top of the grille. I wouldn't worry about it. Also snorkels are more for preventing dirt from getting into the filter than for water

I'd be less concerned about air intake than maybe extending your diff breathers, making sure your xfer/trans breathers are goodntight and prepping your fan so it doesn't torpedo your radiator when/if it hits water.
Make sure you don't cut too much of the passenger side fender liner. I extend my intake using 4" to 3.5" silicone elbow and some plastic pipe to pickup at the rear of the fender.

Any threads/youtubes on how to do that? This is the first vehicle I've had interest in modifying so I'm learning still.
Did you measure airflow before and after? I'm curious how this affects the intake.
Don't have equipment to measure it. But my calibrated right foot did not notice any difference

If you have Techstream or any OBD app you could look at the MAF level at Idle before and after. Would give you a good idea if it's able to get the same amount of air in as easily as before.
Also - do you happen to have any pics of your install? I'm interested in trying this
At low RPM it would be zero difference. It's AT full WOT 5000-6500 RPM where it might cause some issues.
This is how Brian S did his
Picture of the area behind fender. I think I stole this picture from Kichiro Prado conversion
This is how mine is during mock up. I end up not using the clamp. It's tight enough to the fender that the elbow would not move.
@Jstawgn Thanks! That's exactly what I was looking for.
So it looks like the fender intake area doesn't get much, if any, "high pressure" air flow under factory setup anyway right?
I don't see any obvious path where air pressure from driving would be making its way through the wheel well and pushing in to the intake.
All that to say, if it is just "statically" aspirated (for lack of a better term), then moving the intake further back shouldn't hamper it very much?

@GX0R any luck? I'm not wanting to install a snorkel either. '08 470 here.
Saw Ripcord on his Tacoma do the cowl snorkel and I really like that. Our airbox and filter is different than the Taco but would love to figure out a way.
It would raise it about 6" and push it further back.
I reached out to Ripcord and no problems with rain or snow and he gets out in the snow a lot and camps. Wakes up to 2" or more of fresh snow and no problems.

Like Bralow said, actually there is no high pressure air flow from driving or any outside form other than the one created by the engine when "aspirated" ambient air inside the combustion chamber. I don't believe in snorkel, looks nice, but that is. By the time you hit the OEM airbox you might be at 3 feet of water. That is not the kind of fun I'm looking for.
Resurrecting this one from the dead... How long was the poster tube? I've picked up a couple 12" sections of 3.5" tubing, and they seem really short. Even found oa CARBON FIBER one! hahaha
The tube I got was 24" I have to cut 3 it down quite a bit. Maybe 16-18". Sorry did not really measure it.
Bringing this back to life again! How has this been working now that you had been running it for a while? Any issues? Anything you would do differently?
Haven't got the need to go deep and I still run fully intact fender liner even with 35x10.50 tires. Hopefully never have to go deep. There are a lot of other stuff that would get damaged if water get inside the vehicle.
I am pretty sure it would be much more protected than OEM.
I'm with you on that! No desire to go deep but I will have to trim the fender liner a bit and just wanted to do this as a preventative since I don't want a snorkel. No issues with airflow at all?
Not that I can tell. Very very seldom I run this engine at high RPM and I cannot tell the difference anyway.
