Here is a pic taken after I pulled my air filter for inspection from Memorial Day weekend at Silver Lake Sand Dunes on my ’15 1k XP4! I was very surprised to find this much. I don’t think it is possible for the sand particles to go through the Frog skin pre-filter material so it must be getting sucked in from around the cover that the frog skin is attached to? The filter did however do it’s job as I found no sand inside any of the tube going to throttle body. Another thing I did not like was that Polaris designed a air filter that is not hose clamped at the flange? When I pulled the cover off the air filter was kind of hanging down which could have made an opening at attach point. Are you duners getting similar results? Should I look into a aftermarket filter?
