Alfa 156 1.8 Air Filter Housing

[Armchair Expert]

Need the above, pulling my hair out at Google/Bing as I can not find the part or the part number.

Found lots and lots of part numbers for everything around it but not the housing?

Anyone help eithe by pointing me to the part number, or second hand or new parts. Found one new one for £180 but that is more then the car is worth
