Basically on uk cars the follow applies
1 There is no hose on the front of the air box
2 The screws are standard cross heads not torx
3 You don't need to undo the intake pipe
4 You don't need to unplug the mass air flow sensor.
Just undo the 8 screws and lift up the top of the airbox and move it to the side while you remove the old filter and slot in the new one. Move the top back over and seat it back in place. Retighten the 8 screws, Be gentle though as they go into plastic so dont over tighten them.
