First off the Ridgeline doesn't have a MAF sensor... it uses a MAP sensor.
Secondly, if you had enough restriction in the old filter to make a difference at idle you had serious filter problems to start with. A filter change will have the least affect at idle speed and/or roughness.
Whatever the reason for your idle to "smooth out" and your fuel economy increase the filter is not the cause. It's more likely that your local gas station switched from winter to summer blend, or you changed your driving style slightly trying to justify the filter to yourself, or a hundred other things that would be more likely and logical than a filter change.
