These CFD designed and tested Xtreme Flow Wickers are molded of durable polyurethane and are 3D designed to fit your C5 Corvette Part number C5T1HL hood vent kit. Using Computational Fluid Dynamics (CFD), Trackspec Motorsports was able to increase hood louver flow by nearly 480%! By adding the 1" wicker and wrapping the 3D design around the front of the vent, we were able to concentrate louver flow and cause a burst of energy that increases louver flow. This increase of energy is then passed on from louver to louver, exciting the air behind the next louver and causing mini vortices that create vacuum behind the louver blades. The result? Xtreme Flow!
