These Mk II Roadster Hood Louvers are custom made to fit your Mk II hood!  The outer edge follows the profile of the hood perimeter while the inner edge is parallel to the center-line of your car to match up to your racing stripes!  These louvers don’t just look great—-they offer significant area to vent heat and pressure from under the hood!   These Hood Louvers are very simple to assemble and install.  The parts are shipped flat and they take about 5 minutes to assemble.  Before they are formed to shape, use them as a template to scribe your cut-lines onto your hood (I would recommend ending the cut about mid-louver on the front blade and then enlarging the opening to taste after you form and assemble the louvers), cut the opening in your hood, and simply install these louvers from below and bond the perimeter of the louvered panel to the underside of your hood.  Hood cut-out is approx 13″L and 6.5″ W at the rear of the panel and 4.5″W at the front of the panel.  Made from .080″ Aluminum, you can easily polish them to a mirror finish while they are still flat, or leave them in their natural finish and have them painted or powdercoated for just the right look for your car.  The louver blades extend up to be slightly past flush (proud) of the top hood surface.
