There was a time I used to do a lot of car maintenance, but in those days a Sinclair ZX81 computer with 1 Kb of memory was considered a supercomputer.
So there was an element of trepidation before I started.
Removed front wheel - easy.
Removed inner wheel arch - a doddle.
Found airbox, no cable ties or clips, just four screws holding the cover. Removed those - easy peasy.
At this point I made the mistake of thinking this was going to be a peice of cake and I would have the whole job boxed off in half an hour.
A case of premature congratulation.
Three sides of the cover were loose but the side closest to the wing would not move. I tried to use a light to see the problem - no chance.
I tried sliding my hands down the narrow gap to see if I could feel anything - no way. My knuckles now look like I spent the morning in a cage fight.
The only option was to remove the plastic undertray, in the hope I could see what was holding it. Whilst it gave me greater access I still couldn't
see where it was held because it was in behind the bumper. However the better access did allow me to vent my frustration by waggling the airbox more violently. It finally admitted defeat and came apart.
So four hours later a new air filter is installed. Just not sure what to do with the bits that were left over.
