I expect that to work on the playa in a dust storm about as well as a rainfly keeps dust out of tents with mesh windows.
YMMV,IANAL, I didn't stay at a holiday inn express last night, etc. That said, I do work on cars as what passes for a living these days.
it's hard to describe this precisely, but a downturn that traps dust before rising up to the intake is a proven device.
The last car I drove on the playa had a well enough shrouded intake that I never found all of it and it picked up no detectable dust.
No doubt there was some in the throat somewhere, but not on the filter.
i couldn't get the blue tape to stick to anything last trip.
A simple downturn by itself wouldn't be enough without shrouding.
Permanent filters aren't necessarily superior as filter materials have improved.
The reason for using them is mostly cost or improved air flow with larger sizes.
I use disposable ones mostly, including indoors.
Lifespan on the good inside stuff is five years to infinity though.
An exposed k&n will not always stop hardware, in spite of the metal mesh.
If you have any doubt, I suggest stainless mesh as a guard.
I'm not up on newer vans, so can't be too much help.
I would buy a full size if I was buying one myself.
I would urge you to get what you really want, even if it means special order or modifying the interior.
It's usually cheaper than dissatisfaction.
Special orders often come in in meticulous condition, compared to standard versions, in my experience.
