Hi. New member with 2004 Boxster. Looking for name of part.

[zatoichi66a]

Hi. New member. Own a very cared for 2004 boxster (always garage kept with cover). Only 47K miles--second owner. Recently noticed that an external part is missing, and having trouble identifying the part. Attached is the picture (if I attached correctly.) The part appears to be a flap between the rear trunk lid and bumper. Hoping to find a part number, and a place that can match the grey color. Any help would be appreciated. With part in hand, is this a DYI?




[Also, forum is a great site for information.

Thanks in advance. Best regards.
