From realoem.com this is what I see:
-Spark plug, High Power NGK ILZFR6D11 6 03/2007 12120032137 ENDED
-Spark plug, High Power NGK PLZFR6A11S 6 08/2009 12120035915 ENDED
Does it mean that I can use any of them?
Don't really know what ENDED means?
Unless you've replaced all your coils with the latest part, then the latest plug you can use is NGK PLZFR6A11S (as you can see by the dates above, it superceded the other plug.)
As to why they are both ended, refer to this post: http://www.e90post.com/forums/showthread.php?t=174217
