1970-72 Oldsmobile 442 Cutlass OAI Air Cleaner Rubber Plug This is the plug that goes into the one side of the air cleaner base. If you had a car that had ram air and the PCV valve in the valve cover. All the outside air cars had the bigger air cleaner base with 2 holes punched in the side. The cars with the PCV valve in the top of the valve cover had one of the air cleaner holes plugged. This is that plug. This is an exact reproduction part with the 5 nubs on the face and the letters KE on it.
