Quick question for you guys. I bought a 03 SVTF a few months ago. I have reason to believe that the IAT (integrated in the MAF) has gone bad. Most likely due to one of the previous owners over oiling the K&N.

Just double checking that the SVT MAF is not the same as the one in standard foci. Or can I get any MAF that fits the year. I'm assuming its the former but I just want to be sure!

Thanks

Ah, I also just realized this probably should be in the SVT Performance section, not the general section. My bad. Can someone move it?

The MAF sensor is SVT specific.
The original part number found etched on the sensor is 1L5F-12B579-AB
The re-manufactured Motorcraft number is AFLS183RM.
If you have access to a Scan Gauge you'd be able to see the IAT's and determine if it is working correctly. If the IAT sensor fails it will throw a code and the car won't run.
CRC Mass Air Sensor Cleaner would be my first move.

You can always just clean the MAF.

Also, I've run a standard Focus's MAF in my SVT without an issue.
