you could take two GM intake air temp sensors (three wire devices i
think? 5v supply?)  and mount one before and one after, then use a
digital multimeter with a switch.  voltages translate linearly to
temperatures, but you'd have to figure out two temperatures to figure
out actual degrees.

on the upside, there is no cheaper way to do it.  oh, you can use
water temp gauges for the readouts too, but their range is not necessarily
what you're looking for.  GM air temp and coolant temp sensors (on modern
vehicles) have the same connector and same voltage-temperature map.
