Ignition coil part number

I have an 08 N54 135i and I'm planning on replacing the spark plugs and coils but am confused about the correct coil part number. RealOEM lists the Delphi 12138616153 part which looks very different than the current Bosch coils. I ordered this kit from ECS and it has the part number 0 221 504 464-076. Where does that version sit in the coil revision lineup?



This post from Aug 2014 lists both the 0 221 504 464/00124 and 0 221 504 407/00044 as current so I'm confused.
