I can't for the life of me figure out what this piece is called, or what the part number is.

The piece is one of the little clips that the two bolts/machine screws thread into that hold the main cowling on in the engine bay (the cowling underneath the cabin air filters). I dropped one of the clips in the engine bay and it's nowhere to be found.



It's hard to search realOEM or the archives when I have no idea what the piece is actually called.

I assume I can buy these at the dealer?

Try this illustration on RealOEM: I think item #17. P/N 46637651465 would be my guess. BMW calls the part a plug in nut.

You can also get them in the hardware section at Lowes or any good hardware store.

They are called spring nuts. Type "U".
