SIDE UNDER SPOILER IMPREZA 4Door(GJ)

This aerodynamic plastic spoiler is installed under the genuine side sill spoiler. It controls the flow of air past the side of the body at high speed and improves driving stability. It was designed under the assumption that the genuine Subaru front under spoiler is also mounted on the vehicle, and its performance was verified after multiple wind tunnel tests. It has a semi-glossy black coating, with the STI emblem toward the rear.
