This classic design not only looks great, but will actually enhance the performance of your bike. Features include backplates with air-horn style radiused entryway and the dimpled cover with air directional cone on the inside help maximize air flow by giving intake air an efficient, easy path to follow into the carburetor. If you cant get an S&S carb, you can at least get your stock one to breath like an S&S. Includes all breather fittings and hardware for installation.
NoteFits Harley-Davidson EFI Big Twins 02-later (not Touring 08-later) and carburator Big Twins 93-06
