From someone's air intake thread, it was brought forward that the panel air filter has more surface area than a cone.
I wish I could measure my panel.....but my car is not yet back to me, hopefully tommorrow. But I am curious on what size your guys' cone air filters are.
Someone measure the 325i 's panel filter, and then whoever measure the length of the cone and the diameter, and whether or not the end is open or closed. Then it's simple geometry to find surface area.......
But if the panel has more surface area, the "Porsche Motorsport" or "Cheese-grater" mod might be the best, while also cheapest intake mod.......
