Hooker 8525-1HKR exhaust manifold for the 1958-1967 Chevrolet Impala V8 4.6L, the 1962-1969 Impala V8 5.3L, the 1968-1969 Impala V8 5.0L, the 1969-1974 Impala V8 5.7L, the 1970-1974 Impala V8 6.6L, the 1971-1973 Impala V8 5.0L and other vehicles collects exhaust gas from the cylinder head ports and carries it into the exhaust system. This small-block Chevy manifold is designed for rectangular port heads, including standard straight and Vortec straight plug head designs.
A visible crack at a port, a ticking noise from the engine bay or an exhaust smell can mean the manifold is worn out. A blown manifold gasket, a loose downpipe joint or a damaged cylinder head port can be behind the same signs, so find the actual leak before you buy.
This manifold is listed for a wide range of Chevrolet, GMC and Pontiac models, including the 1967-1969 Chevrolet Camaro V8 4.9L or 5.3L, the 1967-1974 Camaro V8 5.7L and the 1969-1973 Camaro V8 5.0L.
