As far as I know, the K3 filters are not intelligent,
the K3 has no way of knowing what the filter is other
than by your setup. If the FM filter was defined as a
5 khz filter, the K3 would probably send the signal
through it and the signal would probably be spectrally
purer than the vast majority of the gear that's being
used on AM today. But the only way to find out would
be to put it on a spectrum analyzer. Elecraft has
spoken of removing the firmware block at some point in
the future. There is also a block that keeps you from
transmitting out of band, which is annoying when
you're
connected to a dummy load.

The current firmware blocks the use of any foilter for
AM Tx other than
6 kHz.
