WARNING: Cancer and Reproductive Harm www.P65Warnings.ca.gov

The BLOX Racing vortex generator is molded out of ABS plastic and is designed to be used as an OEM replacement. This aerodynamic piece will direct turbulence to correct areas of the rear of the vehicle and generate extra downforce.

The BLOX Racing vortex generator is a direct-fit piece and highly recommends using 3M™ exterior mounting tape for installation.
