Hi, I apologize for such a lame post, but I am in a bit of a pickle...
I am trying to remove the black plastic air filter box from my 1980 928S Euro,
and I can't ID the final fastener on the center front of the bottom half of the air filter box. It is deeply recessed, I can't get a visual on it, and to add insult I can't get PET to load on this computer due to screen resolution limitations lol.
Any ideas?
The bottom of the box also had 2 13mm bolts, but this final centrally-located fastener is in a deep recess centered at the front/nose end of the box.
Thanks in advance, as always.

Are you sure you don't mean the long bolt on the top of the plenum that goes through to hold it down?

Mark,

Very possibly yes, the fastener does appear to run down through the rear/tail section of the plenum,
thanks, is it perhaps an Allen head bolt or a Torx bolt?
Thank you
Dan

The stock bolt has a standard hex head

Disclaimer- I know nothing about early cars, but PET shows two different aircleaner bottoms, 1 for 78-79 K-jet cars and 1 for 80-84 L-jet cars.

Which components look more like yours (and if it's the upper pic, then I'm confused about your '80 S having the early airbox on it..):



78-79 (with the big-*** hex bolt highlighted)



80-84:

The fastener is situated deep in the black plastic box.... it may be better described as behind the plenum now that I think about it?
It sits in the middle front, and in this photo from the driver's side, it projects back at around a 45 degree angle?
I don't have a tool slender enough to reach in there, I may be heading to buy a 1/4 extension?

Agan, Thanks. Dan

To remove the lower air cleaner you need to unscrew the 2 bolts inside and remove the long bolt that goes through the center plenum ( shown in the bottom of your picture) Thats it
