These guys aren't replacing alternators every trip, and if you do it right, nothing to worry about in the interior, especially with the wash out floor. Just a little seepage, if that, and pull the plugs...I respectfully disagree.
What percentage of folks running snorkels FIRST take care of all relevant vents and electronics? Perhaps you will break the mold here and be the one guy that does. I guess good on you if you can significantly increase the true/safe water fording depth of your rig. The Raptor and Everglades and 37"/36.4" respectively so fully covering ones tire. Do you need better than this? Anyway, the typical lack of other prep is precisely why I said "they don't work". It was shorthand for they don't work for how 99.5% of people install them. With all of the prior discussion here that should have been mostly obvious.
Now once you do all of the prep work to increase water fording depth you have two quite large barriers left.
So, once you have breathers, electronics, sealed airbox, alternator waterprooofing and have no problems from a swamped interior AND you finally are pushing the water depth or fording wave into your factory airbox, I can see some potential benefit of a (fully sealed) snorkel system.
- Alternators: Despite a deflector added on some year/models of Bronco, there have been multiple reports of deep(ish) fording ruining alternators. Do you have a plan to essentially water proof yours?
- Cabin water intrusion. If you are going to this depth, you should probably be prepared to completely swamp the inside of your rig.
Until then, again, I disagree.
Lastly...
Adding a secondary filter to an existing filter does not in itself prove that a snorkel is actually functional. You could simply wrap your existing filter with a fitted/disposable type of cover, which is a real product. If you are willing to sacrifice having a lot more flow restriction in your intake system, then sure, that can lead to better filtration.
It might not be your thing, but to say they are fake overland accessories or don't help dust getting to your filter is just nonsense.
Now if we are talking about the Airaid snorkel that doesn't even touch the factory inlet, yes, poser and useless overlanding "kit"
