Violet L. ★★★★★ Oct 21, 2026

The fitment on my 2012 A4 is spot-on—no rattling even at highway speeds. They really do cut down on wind noise while letting fresh air in, which is exactly what I was hoping for.

Madison ★★★★★ Oct 20, 2026

Installed these on my S4 and was pleasantly surprised by how snug the fit is—no rattling or loose edges even at highway speeds. The dark smoked look blends perfectly with the black trim, and I’ve definitely noticed less wind noise when the windows are cracked.

Finally found window vents that actually match the aggressive lines of my A4. The precision fit was spot-on, no gaps or rattling even at highway speeds.
