I was thinking about this today. Would trying to increase airflow through my hood vents improve aero somewhat (in lieu of a grill block), as more of the air entering the grille would be able to pass through and exit cleanly, rather than packing up and bouncing back out?

I might try spacing the drip trays on the vents down a little this afternoon to see if I can get more air out through there.
