Airflow

Airflow is important in 4 different areas.

Cooling system airflow: Without this, the engine overheats while running and ruins your day and possibly your engine as well.

Engine intake airflow: Your engine likes plenty of fresh, cool air flowing into it for the combustion process.

HVAC airflow: If you enjoy heating and cooling, proper airflow here is a good thing.

Vehicle Drag(airflow resistance): Our bricksvans have to push a lot of air out of the way. You increase drag with most exterior accessories and whenever you put it higher in the air.
