What data do you need? The K&N filters have less sq in of filter media, yet they claim to flow more air. Right? That's why you buy a K&N - to flow more air? So, if it flows more air, how does it do so with less square inches of media?
The holes are bigger! Bigger holes means more dirt. Fine dirt at that.
You can hear the turbo whine! Why? You've opened the door, figuratively speaking. The open door is letting the dirt in.
Hope you don't live near the beach or the desert.
Good luck.
