APR Performance Subaru WRX/ STI Vortex Generator 2015-2021

This APR Performance carbon-fiber or exterior trim component is application specific. Confirm the exact vehicle, mounting location, dimensions, finish, attachment method, included quantity, and any transferred factory parts before ordering.

Key Features

• Note that if you have a 7 inch Starlink headunit, it will not fit.
• However, if you have a 6.2 inch Starlink radio, it will.
• APR Vortex Generators help to guide the air flow on cars with very steep drop-off angles between the roof and the rear window.
• Air flow has a tendency to become turbulent as it separates from the surface of the car in this region.
• The APR Vortex Generator helps to reduce drag and improve the effectiveness of the rear wing by delaying the air flow separation and reducing turbulence.
• This turbulent air causes drag and reduces the effectiveness of a rear wing.
