This is the good looking duct you see on many race cars. It is a way to duct cool air to your carbs, brakes or shocks. The duct accepts a 4" hose. Made of aluminum with 1/4" screening to keep out the big rocks and bugs. It is held in by using your original lamp retaining rim. If you need this rim we have them in stock, use part number OMR-301.
