  • You act like the bottom of a car is hermetically sealed.

    These things act as deflectors for debris and channel airflow better. There may be nominal protection for belts, but that’s not a massive factor given most belts are behind the fan and aren’t likely going to take damage or get damaged. Particularly given the break angle from the underside of the car and where these things are positioned… neither this photo, nor the person’s attitude, connote that this is a performance vehicle.

    Few non-aircooled cars require flashing for cooling, either. Older Porsches (993s and prior), aircooled VWs, Corvairs, and other aircooled cars need proper flashing to vent and restrict airflow. Water-cooled rely more on the radiator, thermostat, and fan.

    Edit: typos and shit.
