I like K&N filters way better than paper filters. Cleaning is no hassle for people who aren't lazy. They make the pre-filter wrap for dusty conditions.

They do make a 10" filter or really close to it. I used it on my old Duster for awhile. You can search K&N filters by size on their website.

I'd suggest dumping the 10" setup and go with the K&N 11" Extreme Top filter setup if you have the room under the hood for more airflow.
