Best oil kart filter for extreme dusty track

Race at an extremely dusty private track and just messed up motor because of it. Whats the best airfilter ( understand oiled filter needed here) in yall's opinion
 
We only use K&N filters oiled with an un oiled tight knit foamie. Last race was so bad couldn’t see the karts on the track, not a single spec of dirt inside filter.
