I like the Amsoil EAAU4095 -EA with a prefilter EAPF12 -EA, this makes a great DIY setup with 4" exhaust tube to make the piping. Really simple, resists water, dry media, and filters more air. Plus this is a cleanable filter with light air pressure. Filter manager gauge fits right in the end hole so you still know when to clean the filter.
The pre cleaner is water resistant also.
I have been running this setup for over a year on gravel roads and still can't even see a difference in the filter minder gauge. I have cleaned it 5 times (the pre filter and 2 times on the actual filter). I am yet to see any dust on the inside of the tube or filter.
