if he calls you again tell him corys here in london has a bunch of 4.6 tbirds and crown vics with the 4.6 and mass air
 
Brian, Im pretty sure all Mass air flow sensors are the same from 92-5 SC's and 94-97 V8 tbirds
 
If that’s so I have some hear
I told the guy that I have up to 92 3.8
He was talking to ford and He seamed to think they were different
Maybe Ed will clear it up for us
Thanks
Brian
 
Looks like the p.n. is specific to 3.8 NA and 4.6 in 94 / 95 Birds and Cougars. OEM service part number F4SZ 12B579 A for reference ... an original would likely be stamped F4SF 12B579 AA.


cheers

THEY ARE NOT THE SAME
the part numbers for a 3.8 bird and 4.6 bird are the same but there calibrated different i found this out the hard way on my 4.6 i had one go bad and i found a 3.8 one with the same part number and it ran really rich until i changed it to a 4.6 one
 
Why does he think he needs one?
If his car is just idling wobbly or down on power, tell him to clean the MAF wires with a q-tip and windex, put in a new air filter, and flush out the idle air bypass valve with throttle body cleaner. If the car's just suffering from lack of maintenance, it'll smooth right out and will feel like he picked up 20 horsepower.
 
more then likely he is suffering from the typical running rich problem they had in 94-5.i was having this prob with mine and only getting 18-20mpg.i had to change my dpfe and egr control solinoid.now i get 27-30 mpg and the cars runs like a dream but still dosen't hold a candle to my SC's
