Changing spark plugs

[Lexmark]

Hi! I need to change spark plugs in my nissan micra K12 (1200cc) but after some hard trying I wasnt able to remove that plastic cover which covers those plugs. I removed all visible nuts but it still doesnt move. All help is highly appreciated. Thanks in advance.

I looked and found two threads before I posted. One of those threads got answered with a long post of boxes(?) and the second thread starter got photos of procedure via email so it didnt get me anywhere. I got all the visible bolts off but still the cover keeps hanging on something. Thanks.
