Blox Racing Vortex Generators work in tandem with an OEM or aftermarket wing to improve downforce. Sports sedans often have a steep rear windscreen, causing a condition where air prefers to travel straight backward off the roof, rather than following the contours of the vehicle. To get the most out of a spoiler or wing, air must travel down the back window and over the trunk lid. A vortex generator does just that – it encourages airflow over the rear lines of the car. 

From the factory, the WRX and STi are both equipped with a spoiler. A vortex generator allows you to take full advantage of it, or your favorite aftermarket wing. Blox Racing Vortex Generators increase downforce and look the part, because Blox believes you should be proud of aerodynamics!  

3M™ exterior mounting tape is recommended for installation.
