I did some research on the K&N round filters with offset flanges, even made some paper cutouts. I know one largest model that will fit, it is 7" OD, 4" height (filter media) with one offset 3" intake. But even this largest round filter will not increase the surface area by much, compared to the drop in filter.
Since the stock air box is designed for the flat drop in filter, I must give up and continue to use the aFe blue high flow drop in. Maybe someday when the price of the new aFe stage 2 drops down, I will get one.
BTW, I do have the Dinan Ram Air Intake style air duct drawing cold air from the brake duct, so I have no complaint about my intake at this point.

so how much surface area of the stock euro drop in filters are?
