This wind fairing is the perfect fit for my 2020 WRX with OEM Thule Crossbar Set. I have already recommended it to many of my friends without a deflector. The sound from the bars was almost completely eliminated and it improved my gas mileage as well. Install is very easy, within 10 minutes of receiving my package I was out taking it for a test drive. It also makes the car look a lot better, I like the look with the deflector on much more than without any roof rack. I was planning on removing my rack when I didn't need it but after putting this deflector on, I have no reason to take it off; the noise was eliminated and my gas mileage is basically the same as it would be with no rack. Very happy with my purchase, if you're looking for a good wind deflector then look no further than this one.
