     These could correctly be called "the part that Porsche forgot", because if you have had your Boxster for any length of time, you know how vulnerable the bare painted door sills are to damage, especially from scratching.  These beautiful door sills are thick, brushed-finish stainless steel, and are a perfect complement to the Boxster appearance.  We also have them in carbon fiber, for a unique high-tech look.  On either stainless or carbon fiber, the Boxster logo is subtly understated.  The pictures don't really do the stainless steel sills justice-they are hard to photograph.  When you buy your door sills from Pelican Parts, you can rest assured that these are the genuine article, made in Germany, with a Porsche part number (Figure 1).  Be aware that there are some thin, low-quality door sills being offered by other vendors.

     The sills have peel-and-stick tape on the back.  Before peeling the cover off the tape, test fit the sills.  Move the sill fore and aft slightly to get it positioned where it makes full contact, and mark one end with a piece of tape to ensure correct positioning (Figure 2).  There are some sharp edges on the bottom of the sills, so be careful when you test fit them not to scratch the paint (don't ask how I know this).

     When you first look at the sills, it appears that there is no left and right.  In fact, one end of the sill has a gentler radius to the outside edge, which I think is meant to be the rear end.  Here is what the sill looks like installed wrong (Figure 3).  This sill goes on the other side of the car.  It can be removed and repositioned, but be careful not to bend it.  After you are sure the sills are where you want them, apply firm hand pressure to bond the tape, and peel off the plastic protective film.

     The sills really dress up the car-especially with the black interior (Figure 4)!

Comments and Suggestions:
cholo Comments: Many years ago someone installed these plates in my recently bought 996. Apparently the plates detached and a previous owner used an adhesive to re-attach them; however, they use a cheap adhesive or did not properly prep the surface since the plates are loose again. I would like to purchase a new set of carbon fiber plates and would like any tips on removing the old adhesives and properly prepping the surface for the new plates. Any ideas?

  Followup from the Pelican Staff: Try goo gone or goof off. These are as gentle as it gets. I also like using rubbing alcohol to remove adhesive. - Nick at Pelican Parts  
Eddie Comments: Do you have sill plates for a 2006 Boxster 987 or will this Boxster 986 sill work?

  Followup from the Pelican Staff: I'm not sure, but if you contact our sales department at 1-888-280-7799, they will be able to get you the correct part number for your 987. - Wayne at Pelican Parts  
Mike Comments: Hi,
How much would a pair of stainless steel sill plates with the Boxster etching i.e. The one shown on this page, cost?
And what would the postage cost to Australia be?

  Followup from the Pelican Staff: We sell these in the interior trim section of our Boxster catalog. Our shopping cart has an International rate calculator that you can use to figure out how much the shipping will cost you. - Wayne at Pelican Parts  
Bart Comments: Your link to buy the part only has pictures of a carrera sill plate, but has two options listing square and oval boxes, but your photos here don't seem to have either?

  Followup from the Pelican Staff: Those original ones may not be available from Porsche any longer, the link to the door sill plates we have is here: - Wayne at Pelican Parts  
Darryl Comments: Hello there, I own a 97 boxster and was wondering if they would fit. I live in Australia Adelaide and would like to purchase if shipping costs and price was reasonable.
