F32 435i Intake differences

Noticed different part numbers listed for intake mufflers based on options. Do MSport vehicles really have different intake mufflers?







Also noticed these 2 intake pieces have the same part number yet are visually different.



PART# 13717605654











PART# 13717605654



Extra Inner Rectangle with what appears to be some type of spring





PART#11122334344



And the MPPK intake muffler - What a joke
