I was looking at using some 3" flexy hose to re-route the intake from the bottom of the air filter box, but can't work out a safe place to have the intake opening.
Back to the drawing board...
When I lifted the bonnet last week (to install the radiator protection mesh) I noticed the muddy water stains in the front of the air intake following the creek crossing we did on the Murray Mouth Trip. This was with a water depth that didn't come up over the bonnet even with a bit of bow wave. So even the stock intake doesn't look too safe, especially if the water was even a few inches deeper.

Re: Air intake design & modifications
Kev,
Great idea, I'm looking at doing something similar right at this very moment, however not as large as that
My first observation is that I hope you haven't cut off to much air getting to your radiator.
What I have in mind for myself is to just bring the alloy down to the first opening on the grill only which should not be much of a sacrifice for air flow to the radiator.

Re: Air intake design & modifications
Thanks guys.
Brett,
I made it from leftover tinplate sheet I had when I enlarged my letterbox recently. Easily found at any hardware.
Yes I have sides in the angled plate with a top lip slipped under the intake scoop to hold it at the top and a bottom lip slipped under the front bumper to hold it at the bottom. Needed simple cutouts to allow all fixing buttons to still fit through.
Here is the template.
Started with the 300x300 sheet, then cut the 50x60 squares out of all 4 corners, then cut the diagonals for the foldup sides.
Test fitted to Exy for rough places for all button cutouts and finally cutoff clearance for bonnet catch.
Noel,
I would not imagine I have cutoff any more airflow than a large driving light would.
Infact, because the other side is still completely open as is the main bottom grille opening, I may have only cut off about 15% of the airflow at the most at a guess.
[Admin Edit]: Added alternative version of template with black writing on a white background for easy printing

Re: Air intake design & modifications
It might be a good idea, but may be dangerous to the motor in any water crossing. It would direct water from down lower directly into the air intake.

Have you noticed any noise increase since removing all these (resonators). How easy is the air filter one to cut off.
Haven't noticed any extra noise Brett.
The air filter resonator I just covered the hole with tape inside the air filter box.
A better way might be to plug the hole by gluing in a sink plug ?
It is easy to cut off completely if you remove the whole air filter box to get to the resonator from the back.

Thought about this too Dave.
Idea was to drill some holes along the top so that air would still be directed upward and the holes would allow the water to spill through if it got too high.
Anyway, creek crossings should always be done slow otherwise the bow-wave caused by any speed at all makes the height of the water worse than it really is.
