The procedure of replacing Alfa156 pollen filter is different between the pre face-lifted and face-lifted models. It is not difficult but not a very simple task either.

To have the pollen filter replaced in my pre face-lifted model, I had to remove the scuttle. To remove the scuttle, I need to remove the screen wiper arm, a few screws and fasteners too.

Take the chance to clean the air conditioning blower and the airbox.

Looking at the condition of the replaced filter, I decided that I will replace it every 2 years onward.
