well, kind of
08+ STi spoiler = 09+ WRX spoiler for the hatch's
The 08 WRX spoiler is now on several of the other impreza models (which is likely the one currently on OP's 2.5i, but I don't think he ever said if he had hatch or sedan)
wing or spoiler is a matter of semantics if its a hatch version of the STi or WRX or any of the other models with the same piece
only with the '11 Sedan STi has the old-school 'wing' returned.
