Yes it does, but because the intake is an open configuration it will not put the same negative pressure on the tract in order to suck air in. In essence, you could block the radiator support opening completely and the intake will continue to perform. I can't vouch for fuel economy in that configuration, but my assumption would be an increase over the Steeda kit with the radiator support open because warmer air burns more readily. Purely speculation.
In a closed box design, the only air that enters the engine must come through the radiator support. By shortening the intake tract, the engine has a shorter 'straw' to suck through. I even found *with my commute and driving style* that when I Newmissioned my intake I actually saw CAI intake mileage (worse mileage).
The reason this thread exists is because of the dyno testing I did on my car through various intake changes. I found no power increase by replacing the OEM filter with K&N drop-in filter but with further dyno-testing I found that removing the snorkel in-conjunction with the K&N that there was indeed a power increase. Transversely, there is no power increase by removing the snorkel and keeping the OEM filter as they are designed to work together quite well. Some members didn't understand what I was speaking of or how to remove it so I created the thread to illustrate.
