The factory intake can hardly be compared to a straw. A bigger nose won't do you any good when the one you have is already large enough to fill your lungs.

I have yet to see any proof of gains for any of the aftermarket intakes on stock or near stock vehicles. Once you've got a tune on the car that might change, but I still don't see the factory airbox being much of a restriction.
