Matthew ★★★★★ Oct 21, 2026

The installation was surprisingly easy with the included template, and the fitment around the mirrors is spot on. It really cuts down on wind noise when I crack the windows on the highway, which was my main worry.

Timothy F. ★★★★★ Oct 20, 2026

These vents completely changed the look of my Focus ST — they give it a much more aggressive stance. The fitment is spot-on, no gaps or rattling even at highway speeds. I can crack my windows in the rain now without worrying about water getting inside.

The precision fit on my 2013 Focus ST was spot-on, no gaps at all. They let in a nice breeze without any wind noise on the highway, and the aggressive styling really completes the look.
