To tear the air filter you would have to have a dramatic and sudden air
pressure differential between the front and the rear of the filter.  The air
scoop pressurizes the entire air intake system, and you engine does not suck
enough air to cause a big enough pressure drop.  The intake system is
essentially a closed system (no flames, I said 'essentially.'  The air will
move in only as fast as it comes out the tailpipe, or as fast as your moving
pistons and valves will allow it to.
