you are welll along the path to muuch better mpgs!!!
the kn filter has no effect on mpg. several threads on that.
the warm air/cold air discussion seems to be on a case by case basis. you can search to see if someone has done a njewer mazda.

But you discovered the 'secret'!! adjust the 'nut' behind the wheel!
