I usually just look up the part number in my PDF copy of the PET (the official Porsche parts book for the Boxster).

Then I take that number and enter it in the search box on the Pelican Parts website.

One of the things I really like about the Pelican website is that it will tell you if the part number you entered has been superseded (which can happen when dealing with the PET). It also gives you a choice of suppliers (there are often more than one OEM supplier).
