I know that the Raised Air Intake makes it better in the dust and such, but with all the electronics in the Discovery II. Would the snorkel help the Discovery keep running in deeper water?

 

It would be one of the things that you'd have to do, in order to ford deeper water. You'd need a wading kit for it, plus find a way to keep all the electronics dry.

 

So how deep can it safely go? Measured on the body (since some of us have lifts?)

 

Check your manual but i believe it is in the 20 inch area

 

On no lift and stock 16's, I have been up to up to my headlights on first entry. The bow wave held and when I looked out the window, the water was right below my door handle. The only problem I had was water got to my oil pressure sensor. Besides that, I was fine.
That being said, see the following disclaimer.
Nothing on my truck leaked prior to my wading that depth. All fluids were changed after. Vehicle was throughly washed after and most electrical connector checked. They were fine. Your results may vary.

 

Not really, no. They will help if they're sealed, but you'll have other issues at the same or less depth.

 

Engine computer is under the glove box and transmission computer is under the drivers seat.

 

X1, 20" or 50cms but without creating a huge bow wave otherwise you'll swamp. Low gear and keep the throttle open at all costs, i.e. don't throttle back or you'll drown the engine via the exhaust so take it slowly. Don't rush into the water with a 'red hot' engine, exhaust and transmission otherwise you may crack something with the sudden cooling shock effect.

 

if you see fish swimming past your drivers door window ya know you've overdone it a bit and gone too deep

 

I had both my headlights fill with muddy water and my truck went through.
