OEM 1970-79 Pontiac Trans Am Pontiac W72 400/455 & Olds 403 Air Cleaner Pre-heater Hose Elbow with Wittek Tower Clamp. This is an OEM part intended for the Pontiac Trans Ams equipped with shaker scoop and fender mounted fresh air inlet. This elbow mounts to the bottom of the air cleaner snorkel and is secured using the Wittek Tower Clamp. The Trans Am elbows featured an angled relief on the bottom - this was due to the lowered air cleaner base featuring a sloped flange - all designed to allow proper clearances (earlier models and aftermarket pieces do not have this relief and will cause an impact with the valve cover).

The piece presents well and will add to your restoration. Best of all, it is a genuine GM part!
