Exact reproductions of HD’s first real air cleaners as used on Linkert carburetors. Choose from the early version without logo, with screw-on or J-slot connection between the chromed cover and cad/parkerized backing plate, or the later version with stamped logo. They come complete with spring and metal mesh filter element. The J-slot versions with riveted-on inspection plate, too. Correct for model years 1935-1940, however they will fit all Linkert M-series carbs.
