These PERRIN Rear Window Vents for the 2015-2021 Subaru WRX / STI are perfect for a couple of things. If you're at the track and need to cool down the cabin without AC, daily driving to eliminate wind turbulence, or stand out from others in the show. Comes in four color, black, silver, gold, neon yellow.
The best part about these window vents is they're not permanent after installed either. You roll your window down, slide these in, then roll your windows up!
