Most Popular 10-1/2W x 3-3/4L Inch for 2018 Subaru Impreza

Received promptly. It appears to be stronger than the original vent with the added feature of a rain guard. Hopefully it will prevent loss if we forget to close the vent while driving.

Installed easy despite my aprehension about making a hole in my rv, vent damper cover will flap in the wind if not latched
