My recollection is that the official interval is cabin filter at each Inspection, or roughly every 30K miles (for me Inspection I was at 34K miles) and the engine air filter at Inspection II, or roughly every 60K miles (I haven't hit Inspection II yet).

In the personal maintenance schedule I've set up, I halved the intervals to 15K and 30K.

Then when I came back from the desert in July (lots of unpaved dusty roads) I replaced both even though I hadn't reached even 15K on either one. Started a new 15K/30K replacement cycle (or sooner if I go back to the desert.)
