I have a long run of  6" diameter scat like hose from the center top of the
grill opening to a large plenum around the 14" X 6" K&N element. We get strings
of rubber, pieces of track, grit, butterflies, grass and unidentified swarf
all around the outside of the element. Any one piece of it would destroy the
engine. The propeller whips up this same kind of material on the take off roll.
There is just no way out of needing the air filter. The no filter ram air up
high sounds OK. If the filter is 100% then an alternate air door is a must lest
the element freeze over.

The picture shows the air intake location.
