Air Filter for GQ Diesel?

The K & N filter is oil type and i would say that it would resist water better than the dry paper type anyday to a point that is, well it saved alot of water going into the Explorer up at Hill End when we did a couple of river crossings (have no snorkle) the airbox is behind the headlight on the Explorer and the water came over the bonnet as we entered the river, our friends Pajero on the other hand drowned with a paper filter, although he did one more crossing than us, boy that filter was soaked. Lesson learnt, always carry a blind (tarp)

Baz.

I was given numerous Foam filters and cages, for main and precleaner.
Used them in the dream of more power, ya know people ya read on here that gain 3000000kw by locking the doors etc, but that goes along with Hiclones.

The only advantage is the are reuseable.

Im back to genuine paper filters.

Have a very good mate who is a Diesel mechanic. 25 yrs with CAT earthmoving trucks, marine and static engines.

He has always said the same thing. Re-useable foam/oil type filters are fine for power but you won't notice the change without a dyno. That's why race engines use them, engine rebuild every 50hrs who cares as long as you win. However. they are lousy for reliability.

I think the way he puts it is pretty good. "If all you want to filter out is house bricks then use the foam/oil filter."

I use paper, and it's a good idea to check the micron rating on any filter before you buy it.
