These are factory Subaru fog light covers for the 2020 WRX STI. The 2020 covers are a more elaborate design than previous years, with a metallic-black painted outer section, and actual mesh in the outer section that leads to two functional vents. The two are interchangeable, so you could put the 2020 covers on a 2018-2019 STI.
Sold individually, left or right. Black plastic, with metallic-black painted outer section. Pop-in installation requires no tools.
Fits all 2018-2021 Subaru WRX STI. Fits 2018-2021 WRX too, if you wanted to remove the OEM fog lamps.
