Hi, today while cleaning the car, I noticed that the cover for the plug elements is missing - you can see it in the photo. Could you tell me what's missing and what the part number is? I can't find it in the diagrams.

 

What do you think is missing? I don't think there is a cover on that side. The only cover is on the left hand side. Or, maybe I'm missing it too.

Edit: I was wrong. Looks like I need to order some covers. :-)

 

Hi Chorcio,
Yes, there is a triangular cover on both side walls of the engine compartment that houses the oxygen sensor connection. Not sure the covers do much other than make the compartment look a little cleaner. It is not really sealed in any way.

Part #20 here: https://www.autoatlanta.com/porsche-...section=901-05

The one on the right side (the "missing part") is also a total PITA to get on and off around the power steering hose!
The left side one is essential as it covers fuses, relays, and the big smoothing capacitor for the alternator.
