Billetworkz 窗戶通風組 Subaru WRX / STI 2015–2021

I was skeptical about how well these would stay on, but the precision-engineered fit is spot on—they clicked right into place on my 2016 WRX with no gaps. The aggressive styling really completes the look without being over the top.

The fit on my 2015 STI is absolutely perfect—they clip right into the window channel with no gaps or rattling. I can finally crack the windows in the rain without getting soaked, and the aggressive look matches the car’s lines way better than the cheap stick-on ones I tried before.

I was a bit skeptical about how much airflow these would actually let in, but the fit is spot-on and the aggressive styling really transforms the look of the car. They cut down on rain noise too, which I didn't expect.
