1989-93 Mustang 5.0 5-Speed A9P Mass Air Computer

This is a rebuilt A9P computer for a 1989-93 Mustang.  

Please note: We would rather rebuild your existing computer if you have one. There are only a limited number of cores that still exist and if we can save one from being junked, that is our preference. The rebuild service is also much less expensive at $225. To learn more about our rebuild service, click here. 

The computer that you are purchasing is a fully rebuilt A9P. Our rebuild process is as follows: we fully inspect it, bench test it with our custom equipment, rebuild it, test it with our monitor, and install it in a running Fox-Body for quality control. This service comes with a one-year replacement warranty as long as our seal is not broken and a chip is not added.

The A9P computers were originally used in the 5.0 automatic or AOD cars from 1989-93, but if you are doing a mass air conversion on a 1986-88 you will also need an A9P.
