The Holley 108-70 is a carburetor heat shield kit for square-bore Model 4010, 4150, and 4160 carburetors. Installed between the carburetor and intake manifold, the .250 in. aluminum shield reduces heat transfer from the engine to the carburetor, helping prevent the fuel percolation and heat soak that cause hard hot-starts and rough hot idle. Mounting gaskets are included.
