Z4MR Engine Air Filter

What's the interval for this? I see "replace microfilters" as part of the Inspection I service, but I'm not 100% that's the engine air filter. Follow-up question, is the carbon filter on top of the engine filter ever supposed to be replaced? Cleaned?

I just bought my 2006 Z4MR at 61K miles, have less than 1k extra on it. I bought a new engine air filter and, tonight when I replaced it, I saw how filthy the old one was. It had a date stamp on it from 2006. It seems pretty ridiculous that the dealership never changed it (plenty of BMW dealer records in the CarFax, including a CPO on the car), but not completely unbelievable. But, this is why I'm doing maintenance myself, as much as I can.
