OEM 1970-72 Chevrolet 396 400 402 454 Air Cleaner Breather Tube. This is an original 48+ year-old breather tube specific to the 70-72 big block models with a closed element air cleaner that has been refinished to a nice appearance.  It retains the correct curvature required for the big lock engines that connects from the valve cover back to the rear of the air cleaner base. It requires a rubber breather hose adapter connected to the top of the tube that in turn connects to the breather filter at the rear of the air cleaner (not included).

This piece presents very well and will enhance your restoration. Best of all, it is a genuine GM part!
