The MkIIIC's front diffuser air management differs in that instead of exhausting the air out the side of the car as is typical, the air is exhausted out the top of the sidepods either side of the cockpit. 
The diffuser air exhausts into ducts located in the side pod.  From the duct the air empties out the top of the side pod. 
A very visual example of the air flow separation and general untidiness of the air that exits the front radiator duct.
