This upgrade is rather redundant, as anyone who buys a brand new MAP sensor from GM will most likely get this improved replacement anyway. But if you have a
mostly all original Fiero, you probably still have the old map sensor. GM's replacement map sensor for the V6 Fiero is the same 1-Bar sensor they use for a variety of other
vehicles now. The part number for this revised map sensor is: 12569240. The GM MSRP is $79.95, but it typically retails for $40-45.
