The air box lid at the MAF connection is always broken on these.

I recently took one from a 4.6 Bosch motor on a P38 and it fits perfectly. Oddly they have different part numbers. The P38 part seems to be made of a better quality plastic.

Hope this helps someone. I have 3-04s and each one had broken tabs at the MAF. Just replaced them all with P38 model lid.

 

PHB102260 is the part number. It's actually for the 4.0 and 4.6 Bosch motor on the P38.

Only the lid is a direct swap though.
