Hi John... I re-read the whole thread and realised that I gave you answers about the oil filter instead of the air filter. I apologise for that.
I also have a picture where the air filter is clearly visible. The picture was taken during my visit to MMC in autumn 2022.
Unfortunately, I don't know the number for the filter. But I would also be interested to know how the air filter is changed.
