06 mustang gt mass air flow sensor problems

I guess I'm a little leery of aftermarket MAFs, but I've never had one. What about the Lightning MAF I've read about? Those are said to work. The Cobra intake is nice, because it removes the interceding variable of the EGR spacer. It would lower the already low number of non-Ford/aftermarket parts under my hood though. I've got all of the 65mm fixins' here, but haven't bothered to try it. Just source the 65mm from a junkyard Explorer/Mountaineer, and convert it over to the Fox configuration yourself, for cheap. You can always purchase both throttle bodies. I would think that with those AFR heads, bigger is going to be better on the inlet side. I put it in my 70mm housing, and now the car runs better than with the stock MAF, and worlds better than it did with the 55mm sensor in the 70mm housing. I also found out that the sensor I needed was in '94-'95 Mustangs, so I went to U-Pull-&-Pray and picked one up. I then researched this Ebay MAF, and discovered that I bought a housing which is probably from a T-bird, with a F1ZF-12B579-AA (AFH55) sensor from a '88-'93 Mustang 5.0. So I threw my stock 55mm MAF on the car, and it ran like it should. However, when I put my GT40p heads on the car, the MAF worked very poorly - the car ran better with the MAF disconnected. It worked apparently fine on my car with an Explorer intake and upgraded exhaust. I learned about this after buying what was advertised as a '93 Cobra MAF, on Ebay. The '94-'95 Mustang and 4.6 T-bird housings are both 70mm, so the 70mm sensors are compatible with either housing - although in general, you shouldn't go mixing and match housings and sensors. And with the '94-'95 sensor, it's plug-and-play. You can run the whole '94-'95 assembly, but then you either need a flange adapter, or to grind off the flange ears. Here is the '94-'95 Mustang flange-style: These housings might have come on a few other models too, like maybe the Towne Car, and T-Bird SC. This setup is better than using the housing from the '94-'95 mustang, because the '94-'95 mustang requires a flange-style connection on the air-filter side, whereas the '93 Cobra/4.6 T-Bird style housing uses slip connections on both sides - like all '88-'93 Mustangs.

If you bring your T-20 bit to the junkyard, and swap the Mustang sensor into the T-Bird housing there, you pay for only one Mass Air Meter assembly.

If you want to run a Ford '93 Cobra-style 70mm MAF assembly, your best bet is to get a 70mm MAF housing from a '90s 4.6 T-Bird/Cougar, and a F2VF-12B579-AA (AFH70) MAF sensor, from a '94-'95 Mustang - all models.
