Any one know where I can find the part numbers for the new boxster diffuser (the 2 black pieces that is attached to the rear bumper) I've tried to call few dealer and ask them for those parts but none of them were able to get me the part number nor what I am talking about.

 

Are you referring to parts 35 +36 ? then the numbers are
987 505 875 00 /L
987 505 876 00 /R
however you might need part #5 to mount them 987 505 853 03 (retaining frame) (G2L satin black)

 

Yes that's exactly what I am looking for. Thank you so much.
