Yes, you are absolutely correct. To 'scoop' or draw air you need to out at least 6" or more. But the advantages are not only that it now actualy becomes functional, it also changes the 'normal' existing airflow benifically. Noticed all the 'sweepings,' dust, junk that acumulates on your motor covers, carb filters etc.? The airflow is up thru the motor compartment from underneath the car. Hot air rises, deck lids retain & hold this captured heat,... slow to excape.... the big "Bunny Eared" scoops force the air down away from the induction, past the exh. and out the back / bottom of the car... this is a good thing...and looks killer. IMHO. ( Will post pics of mine soonest on our very own PIM's very excellent Photo Gallery site ) - Hall claims a .2sec. improvement in quartermile times with his,- they replace the rear quarter windows.
