These 1/8" thick clear Poly-carbonate quarter windows are direct replacements for the 987 Porsche Cayman (987.1 and 987.2) with the addition of a NACA duct and fit in the original window mount. They are ideal in race car builds where you need to get additional air into the engine bay for cooling the often over-heating transmission or the cabin for the driver. The custom GT Racing exclusive size NACA duct is designed to fit a 2 1/4" hose as we had to keep this NACA small to fit the smaller 987 quarter window. The NACA Duct and the window are not assembled. They come with stainless steel fasteners for easy installation or they can be glued in or assembled via automotive foam tape. Weight is less than 2 lbs per pair. Quarter windows are sold in pairs.
