If you look at the amount of flow area you have for air to get in at the top of the box and through the original air intake, it is significantly more than anywhere else in the inlet system. The vast majority of the pressure drop you will be getting is through the filter itself, not through the inlet.

I don't understand why you say you have a cover so heat wouldn't be a problem; if you suck warm air in from behind the radiator, then a cover isn't going to help?
