Measure it.
The stock air box is functionally identical to the aftermarket closed ones. The only real difference besides the filter is the air straighteners , which you can cut out if you want, though that could be why aftermarket randomly reads lean due to the maf getting turbulent air flow.
There is really no difference between aftermarket solutions and stock in the intakes for this car. They suck from the same place. They route air over the same exact path. The much larger cone filters and the air straighteners are pretty much it. But if you keep your gauze drop in clean, and cut your the straighteners out, you'll have basically all the same air resistance as any aftermarket enclosed (cai) solution.
