Chevy Impala Intake Manifolds & Parts

An intake manifold forms a terminal section of the air intake route. Bolted right to the cylinder head, the manifold distributes the airstream among the cylinders while providing smooth and effective air supply for each of the combustion chambers. While the manifolds of older vehicles with mechanical fuel delivery systems were simple components normally including no digital devices, those employed by modern EFIs are quite a lot more sophisticated and use multiple sensors sending info to the control module.

Intake manifold-related problems on modern Chevy Impala generations are much more serious than those of older models equipped with a carbureted engine. That’s because the ECU measures the air entering the engine before it splits in the manifold, and even the smallest leak uncontrollably adding gas to the combustion chambers will badly affect the air-fuel ratio and thus decrease the efficiency of the combustion process. A known issue on the Chevy Impala is a leaking intake manifold gasket that may result in loss of coolant or engine oil or, in some cases, cause these fluids to mix, which may lead to engine damage.
