When installing an aftermarket air cleaner you sometimes just need some extra space to clear the intake from the air cleaner. This 1" (25.4mm) thick aluminum spacer block fits right between the air cleaner and carburetor or Injector body and is pre-drilled to make installation a piece of cake. Fits all models with Keihin CV carburetor or Delphi Fuel Injection, except 2008 to present FLH and FLT series Touring models.
