Nice writeup, but you don't have to remove the entire air filter box just to change the filters. If you also want to clean the throttle body and/or change the belt, the removing the entire box is needed.

I would strongly recommend removing the air filter box and cleaning the throttle body at the same time. My 2009 with 26K miles was not delivering power cleanly and having had the same problem on my 996 I cleaned the throttle body.

There was quite a bit of gunk around the butterfly and cleaning it out made a HUGE improvement to the drivability of the car.
