The Password:JDM Dry Carbon Fiber Gurney Flap / Wickerbill is a short lip that protrudes upward from the upper trailing edge of the JDM 2002-2006 Integra Type-R's factory wing. It’s used to enhance the wing’s down-force characteristics by separating the airflow on the back side of the wing, primarily that which comes over the top of the wing. The result creates a localized high pressure zone on the top side of the wing generating down-force. Care instructions: Please note that these parts are finished in natural dry carbon fiber, which does not include a UV-protectant clear-coat finish. We do not recommend adding a clear coat to our products. We instead recommend applying a coat of Spray-on Wax or Ceramic Coat to prevent water spots / white marks from appearing after rain or car wash.
