Ford KA 2005 air filter replacement
I think I have an answer now, I'll post it for future reference as it is not obvious how to do it !
REMOVING THE AIR FILTER FORD KA 2005
1)
Pull off pipe from rocker box and release it from u clip at front end of air cleaner box.
2)
Undo hose clip and draw back intake hose. It will detach completely when the air box is withdrawn later
3)
Do not touch the Philips screw but observe the u shaped plastic shoulder which surrounds the ‘beak’ and below it is a joining.
4)
Carefully insert the tip of a very thin bladed screwdriver and carefully lever up this moulding, it will then be obvious how the air box is attached to the front cross beam.
5)
Lift up the assembly and withdraw from the car
NOTE
It is possible to open the box by unfastening the spring clips to observe the air filter but to change it the whole assembly has to be removed first
