APR Carbon Fiber Vortex Generator - WRX / STI 2017-2020
This is the APR Performance Vortex Generator. Other than a cool race-inspired look, these actually serve a purpose. For those of you equipped with a larger rear spoiler, or even a rear spoiler with a smaller profile, this generator will help channel the air coming over the roof so that the air will hit the top surface of your rear spoiler to add a little more downforce and aerodynamic refinement. This is why you see some of these equipped from the factory on certain makes and models. Now you have access to the same technology with a nice carbon fiber touch.
