1968-81 Pontiac, GTO, Firebird, Preheater Shroud to Air Cleaner Plastic Elbow. For Heat Riser Tube. This is the heat riser tube elbow, it goes from the air cleaner base to the exhaust manifold pre-heater shroud. One of these are used on all Pontiac engines and the RAM AIR 4 uses 2 of these. These are used on all Pontiac V8's and are a must for a concourse restoration. This is an exact inline tube reproduction made identical to the original.
