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. 

All WRX/STi models from this generation come equipped with a spoiler, however, only the 2013 and 2014 come with a vortex generator from the factory. A Blox Racing vortex generator improves upon the OEM design, if equipped, allowing you to take full advantage of a factory or aftermarket wing. 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.
