Genuine BMW 330ci Wind Deflector and Carry Case in very good, used order. When you drive a convertible with the top down, a low pressure area forms inside the cockpit, while high air pressure remains outside. This air pressure difference then equalizes, causing hair to blow forward (not backward) whenever the top down is down while driving — with the Deflectors, it MAKES IT A VERY PLEASANT OPEN TOP DRIVING.
