4Runner Trailhunter snorkel vs. fresh air scoop (for water fording / river crossing)

kzrman · May 12, 2024

My understanding is that the Trail hunter comes with a fresh air scoop.

This got me thinking about using the truck for river crossings where the water would be above the hood slightly.

I believe that in it's current set up this maneuver would not be doable.

Not being an engineer I half to wonder what it would take to make such a fording possible. IE, how hard would it be to add an aftermarket snorkel and completely seal the air system?

You can look at past generations for a best guess right now. Without a snorkel, the 6th gen engine looks to draw in air from the front passenger fender (usually above the wheel well). There will most definitely be aftermarket options that offer the same functionality as the Trail Hunter.

The other major consideration is extending the breathers of your front/rear differentials as high as possible. Front extensions usually go in the engine bay, rears have been extended to the gas filler in previous gens.

Are you referring to making say a TRD Pro into a Trail Hunter?

I'm just saying you will have an option to add aftermarket snorkels to trims other than Trail Hunter.

Will a delete be offered for those who don’t want a snorkel?

I don't think that driving in water that's over the hood is a very good idea. I'm fairly certain that it's not good to submerse your engine under water. Especially if it's a hybrid.

I concur, but I would say unequivocally it is a bad idea to give your engine a bath.
