Nadda, the '01 is 80mm also. Also, the only difference in the '02+ is the integrated Inlet Air Temp (IAT) sensor. The '02+ is 80mm also. Some will say its 85, but they're measuring the opening at the mouth of the tube, and not at the narrowest point, which is approx. half way in.
Yeah 80mm, the 99 to 2001 are the same and the 2002 and up are different and not compatable the 99-01 intake temp sensor is in the intake elbow after the mass air and 2002 and up is built into the mass air.

Aaah, you're right. C&L went to an 85mm for 02+ but Ford still 80mm
