Stuck at Cape York

I thought that this is the possible cause, if you have seen the shape of the air box leading to the filter box you'll understand that it has little chance of draining out.
Anyone can see, the various RAI are posted here by KristinaM, not exactly tight fitting craftsmanship. There is a bit of seal around the RAI - not what I would call watertight by any stretch:

@AUDIOBUS - That still seems pretty sketchy to do with the existing air induction assembly:

@KristinaM Yup. I agreee. As mentioned, poke holes in the idea! All I was suggesting was, if a CIPP (or other) type of liner between the outer RAI and the inner air box was cheap enough to do and simply gained someone time to correct for poor judgement or an accident, it might save an engine. It's not meant as a replacement for something like the GrenX product.
 
The RAI has two advantages over no intake, besides the air being drawn from a higher position.

The snorkel has a raised lip that loosely fits into the fender opening (top arrow). Second, around the raised lip is a seal, not a great seal, but better than no seal (bottom arrow).

So the odds of the cars with a RAI were better than the one with no intake, when crossing that river. But I would not have crossed that river at that depth with the OEM RAI, period.

The RAI is upside down in this image.

I have been wondering where to put this to a good use and after reading on here, bingo and the light came on. Also View attachment 7915003View attachment 7915004Tazzieman can now measure his lift.
This could have been useful during a certain river crossing. 🫣 Perhaps they need to paint a line on the car. “No H2O above this line. Failure to follow will result in the irrational decision for many people online to suddenly not buy this vehicle.”

Not sure who has had their airbox out before, but installation and removal involves a bit of articulation around the slightly ovoid connection to the RAI chamber.

This junction I reckon looks fine for.a bit of splashing in a well-paced crossing but most certainly not for sustained immersion.

On the other hand sealing (eg with Sikaflex) would make the airbox removal/installation a real headache.

It’s also not a rigid mount so I wonder whether making the junction fixed would pass mechanical stress onto the three plastics studs that the airbox mounts via.

I removed my RAI a while ago, found water sitting in the bottom of it, it collects and holds it quite well, the section that is on the vehicle side has a "duck bill" valve to allow water to drain out. What I did notice is that that part is not sealed against the inside of the guard, so any attempt to seal the RAI from the outside is futile as it will leak from behind.

The opening grille at the top is just a few cm away from the gutter capping. I've watched water enter the RAI from the gutter overflow while washing my vehicle. It's not a stretch to imagine rainwater pooling in the RAI and bottom of the air box if you're travelling in the tropics and get a good downpour overnight. The drain valve should take care of it.
A pre filter sock might be good for more than just dust.
