This is a plug for the differential of a FRS/BRZ/86/GR86. This is used to plug the hole the axle goes into if you are removing or installing a differential.
I used this to test different differentials and remove/install them without draining the oil. It also can be used to transport a spare differential to the track in the back of a pickup truck and it will keep rain water from getting inside the diff.
