The pictures show a 1.8 engine bay. The 1.8s use a hot wire mass air flow
sensor.  Doesn't actually *look* any less restrictive to me. The Bosch ones
are very free flowing--just a tube with a coarse screen on each end and a hot
wire in the middle. The Miata one has all sorts of venturis and stuff in the
middle.
