Of course there is going to be a gain .... nice to see Active Autowerke provide some proof (albeit for an M5).
These are not huge gains ... but they are FREE ... and they are surprisingly noticeable. I bet the engine management software was never tweaked to account for these additional filters, and now the engine runs as it should.
Here's a test for skeptics:
1) stick cotton balls up your nose
2) run 5k
3) remove cotton balls
4) run another 5k
Notice any difference? Class dismissed.

I'll try that cotton ball test and report back...
