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. 

The WRX/STi of this generation is one of few vehicles equipped with a vortex generator from the factory. It is a bold look from a manufacturer; however, the OEM piece is too modest to boast noticeable performance gains. 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.
