Got to be honest I am not 100% sure off of the top of my head and I am not with my bike so I can’t look.
The best that I remember to get the air cleaner off was the following I think
Undo 2 bolts above the box, both allen Key
Then pull it out slightly from the bottom which will release it from a rubber type gromit
Uncouple a small electrical sensor connector
Disconnect the small pipe
Then I think it was a cross screw to be undone on the bracket
All from memory so apologies if wrong, will check tonight tho
