This beautiful radiator shroud from APR Performance is designed to keep air flowing THROUGH the radiator instead of up and over the top of it. The shroud is constructed completely of carbon fiber -- and not that fiberglass-laminate stuff. This is "dry" carbon fiber, like on real race cars, baked in an autoclave for maximum strength and absolute minimum weight. Simple installation. A stunning and functional underhood modification. Fits all 2002-2005 WRX and WRX STi.
