Opinion only:

How long a filter is efficient is determined by how much dirt/dust it has filtered ..years and miles mean nothing as far as I am concerned...
and any system that uses Electonic Airflow Sensing is looking for the cleanest air you can find in order to remain accurate....so, at 5 bucks a gallon, I prefer to change AF more often that not. And I clean them in between changes , along with the box they sit in..........
Overkill ????...I doubt it. You show me a dirty MAF and I will show you a dirty a/f......
