UNI makes good filters, twin air does too but if your in wet and muddy stuff id keep the air box lid on

I found the best thing you can do when in dusty or muddy trails is put an Outerwear for a K&N over the stock filter. I hardly ever have to clean the stock foam filter because the Outerwears blocks all the dust and you can see it.

I'd go with a K&N with a outerwears for that type of conditions
