I have thirteen (13) Z-31 air-mass sensors that were removed from 300 ZX cars with less than 80k miles back in the mid to late ninety's. These cars were in accidents while running and were parted out and parts were professionally packaged and stored in plastic bins in dry storage. I'm asking $65 each for turbo or non-turbo, all you have do if interested is send me your numbers on the bad unit and i'll match them up. Also have several sets of Fuel injectors for Z-31 cars.
