Honda RA106 - exhaust side-cooling vents 08 October 2006
A small, but interesting modification for Japan is these small cooling vents placed in the area close to the exhaust pipes on the Honda. These provide better extraction of hot air from the sidepods, caused by the high pressure of the exhaust gases. Furthermore they actually increase the speed of the airflow in this area by adding a portion of hot, high pressure (and hence faster) air. This is useful in increasing the efficiency of the rear diffuser, helping it to better extract the air from the bottom of the car.
