highly doubt it, different computers all together, different injectors, so basically no.

Odds are... It won't work well.

What size is the MAF? XX mm?

What is the computer catch code for the 03 Cobra?

With that info I should be able to look up the MAF Transfer for the 03 Cobra.
Then you compare the 03 Cobra transfer to the A9* transfer.
If they match, then all is good.




Most likely they will be significantly different though.

The problem is that Ford did not calibrate that MAF to the injector size.
Instead, Ford calibrated the MAF to the computer.
(Only aftermarket MAF meters are calibrated to an injector size)

In order to run a Ford MAF, the computer has to have the correct calibration file. You can modify the calibration file in the EEC, but it requires the $$$ for a dyno tune or tuning software.

The only way to know if the meter will work with your A9* computer is to compare the MAF Transfer file for your vehicle with that of the 2003 Cobra.

I am willing to pull up the files and provide a table for comparison for you, if you can find the info on the 03 Cobra.


I am curious how different they are as well.
