This is the factory trunk badge from the 2002-2005 Impreza 2.5RS. Apply it to your Impreza, or use it to "downgrade" your WRX or WRX STi. Or you could retrofit to your GC/GM 2.5RS.
About 4 3/4" wide x 2" high. Peel-and-stick installation, so you could stick on any car (or anything else) regardless of whether the configurator says "Fits your car" or not.
