A SOUND·ABSORBING AIR INTAKE ELEMENT AIR CLEANER Filters out dust and other harmful air-borne particles, and quiets the sound of air flowing into the car­ buretor. Chevrolet-built engines use air cleaners of one of three types: • Dry Element - Resin~impregnated replaceable paper element type of pleated design for compactness with large filtering area. Element is re­ tained in the air cleaner housing by metal screens. • Oil-Wetted Element - Polyurethane BOTTOM foam or special paper filter element wetted with engine oil for effective filtering. Element can be removed 195-bp Turbo-Fire 283 Dry Element Type for cleaning.
