K&N Weber IDA 48 Down Draft - 5.5 x 9
These assemblies include a base plate, chrome-plated top plate, gaskets, and a replaceable 5 1/2" x 9" oval K&N filter element. Each filter assembly fits one carburetor.
To install, remove the velocity stacks and the center debris screen. Fit the gasket over the 6 studs on the top plate of the carburetor, followed by the base plate from the filter kit. Install an O-ring on each velocity stack just below the retaining flange. The O-ring should seal between the retaining flange and the base plate. (If you are refitting the debris screen, install the second gasket on top of the base plate, followed by the debris screen.) Reinstall the velocity stacks and fit the filter element and top plate.
