Way to go Utah!
It often seems nice when we neglect (or forget) something, then go to change a part and see the good we are doing and the benefits such as better smelling air, more airflow, etc.......
We do not always get/notice those obvious benefits when going by schedule.
I have changed two cabin filters. One on one car at about 130k and one on a van at about 180k. Both were funky and assumed to be from the assembly line.
