I'm considering getting a drop in high flow air filter for my jeep but am concerned about their ability to trap dust compared to paper filters. When spring comes around I'll be using the car everyday for work which involves driving on very fine sandy roads. This sand leaves a fine dust on everything and the last thing I would want is a filter that lets this through. Anyone have any insight into whether drop in oiled filters from brands like K&N, Fram, and Purolator will be able to keep the dust out? Thanks

 

My experiences with K&N with my 2 Ford Explorer's was positive. With filters being oiled they do a great job of trapping fine dust particles. When I used to wheel my old 98 in the dry summer months I never found dirt/dust in my intake tubing.
