Donaldson prefilter, works grear in dust, rain, snow storms...catches everything....now for some 3 1/2 years here in arctic.
here is how one is made (tube from mild exhaust pipe 2,5") and how its installed:
Ron's Range Rover Classic Modifications
I have similar self made setup, pipe cost me some 20e and pre filter 25e...time to fabricate were some 4-5 hours.
These pre filters are used in commercial machines, but seem to work fine also in cars, so far I`m were happy with it
ps. for land rover engines take similar size, this thing need air flow rushing though it so it can create the filtering effect. Donaldson filters can be found in most agricultural (tractor) shops
