Long time lurker here, made a few posts when I bought my 992 in 2022. Just picked up my ultimate dream Porsche a Ruby Star Neo GT4RS. Can't believe it's real. On my 992 and previous 718, especially the 718 the wind buffeting with the windows down is soooo bad. To the point where in the 718 it's frustratingly bad sometimes and I wonder why Porsche didn't do anything about it. I came across a video on YouTube of another 4RS owner talking about these different options for "Foilers" to reduce buffeting. I was immediately sold and ordered a set of the AWE ones. What a difference. I wish I knew about these on my previous 718 because now I can drive windows down without being so annoyed I want to roll them up. Such a tiny thing made such a huge difference. Such a big difference I decided to post about it here so y'all can enjoy windows down as much as I do.
There are a few other companies that make these, including expensive carbon fiber ones. The reason I chose the AWE ones was because of the video I watched saying how functional it was and the low price. No sponsorship or anything going on here, I just think everyone should have one of these no matter who they buy it from if you ever roll your windows down in your 718. This is what I bought: https://awe-tuning.com/products/awe-...he-991-981-718
Anyways, install was cake and they put a blowpop in the impressively designed packaging which I did not eat haha, but A for packaging effort. These fit perfectly like OEM for me. I have about 550mi on the car so far and can't wait to take it to the track this spring!
Included below are a few pics of the car when I picked it up and the diffuser itself. Also a picture of how easy it is to get the interior trim piece off to install. You literally just pull up then remove a single screw! Took me 5 minutes to install both sides.

glad it solved your issue. i do have a question for you. at what speeds did you experience this? is it along the lines of say between xx and yy or is it constant above zz? i've put around 10k on my '17 CS, with at least half of that or more on track, and i can't say this has ever really been an issue for me. it may have happened once or twice that i can recall but in those instances the window was only partially open and that has happened on previous non-pcars as well. a slight adjustment in height and gone. i've been up to 168 on track, windows wide open, and nothing.

I may be extra sensitive but it's a problem when it's really windy or above ~40mph. Not always constant depends on wind, but the more there is the worse it is. It is much worse on the 718 than the 992 in my experience. Only two Porsche platforms I've owned so nothing else to compare to.
I have a set of these as they are local to me. I put them on my Boxster and right after doing so realized that it's a needless mod...but kept them on anyways. Had their gen 1 on my GT4 and i found it helped quite a bit. While i dont think the Porsche has the buffeting issue as bad as some cars (A90 Supra), it does actually work to help disrupt the small amount of buffeting that does happen normally. You'll be surprised at how much "quieter" the cabin is with windows down with these on vs with them off.
