SEC 275 is a reference to which section in FAST the part is located (Section #275), and really helps when navigating the pictures.
The 11925M is a FAST part reference but not the actual part number.
Anyway, here is the pic for section 275, so I can only presume that the assembly highlighted is what you are after (although it does look a little small in the pic).
You can see below the illustration that there are two part numbers for this assembly
11925-AG300 and 11925-AG30A.
Only 11925-AG300 brings up our VQ25det in Parts Master so go with that, although it may have been superseded by the 11925-AG30A part which brings up VQ35de and VQ25dd, ie series 2 M35's.
