The matched pair of intake manifolds are suitable for use on early unit-construction Triumph T120 models from 1964 through 1968. Bore size is 1-3/16″ making them compatible with both Amal 389 Monobloc or 930 Concentric carburetors.
These manifolds feature the correct CEI threads and a top quality zinc plated finish. Correctly threaded holes for the 70-4791 balance pipe stubs.
The manifolds are threaded directly into the cylinder head inlet ports and once correctly positioned, are secured with a locking ring. Threaded stubs are fitted to each manifold and joined with a balance pipe. The carburetors are fitted to the manifold flanges with separate bolts, washers, and nuts. The joint is sealed with a carburetor flange o-ring, insulating block, and paper washer.
