Sure. Once the piston rings bounce over that little quartz particle
at about 60 mph, the oil will pick it up and maybe run it through the
bearings a couple times before it gets caught by the oil filter.

Check the oil change schedule for dusty conditions. I bet it is less
than a 5000 interval.

Maybe your son could help you prove this. Have him switch the K&N
with the stock filter randomly after each fill-up. You check the gas
milage and subjectively rate the performance on each tank. I have to
say that I am skeptical that the difference is as much as you say but
I could be wrong.
