Home-brew pre-filter

I'm at 13,000 miles and just put in my 3rd air filter at $30 a pop, even with blowing it out a few times along the way. Way too hard to get to and too easy to get it really dirty, really fast. I ride a lot of off-road dirt bikes and on my KTM I've been really happy with the pre-filter they have. Works great in super dusty conditions and extends filter changes to at least twice as long. So I went and picked up a KTM pre-filter ($11.99 at my local shop), drilled some extra holes in the snorkel, treated the pre-filter with No-Toil oil, wrapped the snorkel with the pre-filter like a taco and zip-tied it in place. Should be way easier to clean the pre-filter and I'm guessing it'll block 90% of what would normally get to the filter.
