Only reason why most here install the M filters over stock cuz it's shown they flow much better. Hey, You may be right. You may not.

The material is going to be the same with the 50i vs X5M the increased 14% flow comes from the larger surface area size of the media.
If I go to Autozone and order the X5M filters and they look exactly like the "normal" X5M filters then they will undoubtedly flow more than the 50i filters.
