The opening into the intake gooseneck is larger on the 2.1l AFMs.  I
think the mount to the filter box might be different
(adaptable).  Electrically they're undoubtedly similar, maybe
identical; but mechanically they're built to accommodate the larger
airflow through the 2.1l engine so would at least need recalibration
to be correct for the 1.9l.  I *suspect* that a properly working O2
sensor would be able to compensate for the differences though of
course that's not an ideal route.  If you're going with the AFM, a
2.1l filter box and rubber gooseneck would make sense to me.

Mark Drillock?  Do you know about these swaps?
