Chris - It looks to me that the air filters are not in a sealed enclosure to the outside air inlet. Based on other's testing of the airflow through the engine bay, it would lead me to believe that you are still receiving air from under the car as your primary source. Owners, who have been down this path, claim the airflow will be form inside and out your gill at speed. Have you had an opportunity to run an temp probe to confirm that you are getting cooler temps at that airflow location? I am currently building an enclosed system based on other's observations and testing.
The air filter is 10 1/2 inches long and 6" in diameter reducing down to a 4" opening at the front, the front of the filter is open and is a reverse cone inside this is where the air is entering through the side scoop ( see close up picture of the side scoop )in addition the filter is isolated by ( hard to see in picture )steel blister under the filter area that runs it's length and width and then some.You are correct in your observations of the air flow created by the deck lid, but the normal side engine heat area around the headers has been moved to the center of the bell housing area due to the 180 degree headers I am running. The opening in the deck lid also promotes flow through the side scoops. I will next trip out give you actual temperatures in and around the filter / scoop area, but I can tell you it is very cool to the touch. The gill area is behind my scoop.
