This 4 1/2" x 9" oval air filter fits the Weber 32/26 DF series carburetors (DFB, DFD, DFE, DFB, DFAV, etc) as well as the DGEC model. Includes base plate, chrome top plate, and cast aluminum adapter.
The DF series is similar to the DG series, but with a rounded diamond shape lip on the top of the carburetor. DF series carburetors are used primarily in vintage racing; the DG series is virtually standard on current FF1600 and F2000 cars.
