A list of various cars that have various types of MAF censors, 
(Especially the hot-whatever types.) would be very useful when 
junk-yard prospecting.

If you really want to experiment, there were articles in both EDN and 
Electronic Design of air flow meters using common miniature light bulbs
with the glass removed as the hot wire sensing element. You could build 
either one for less than $15.
