The BMW parts department called to tell me that my missing weatherstrip had arrived. I drove over to pick it up and decided to install it while in the parking lot. It took less than 10 minutes. It is a dry friction fit, glue is not necessary. I meant to take a pic of the part but it only goes in one way. The part had F23 embossed on it. Thanks to Sportstick for digging up the order number. I attached a pic of the order invoice.

I think it does reduce wind and outside noise. Since my car came with one already installed on the passenger side, I wanted it on both sides.

It's a boring drive home from the dealer so I decided to experiment with EcoPro mode, which I've never used, and the cruise control. I was amazed that it got 38.7 mpg at an average 71.5 mph. That's crazy! Disclaimer: sometimes it only gets 12 in town due to my heavy foot.
