Industrial upper intake manifold with seal for the 1996 Chevrolet Blazer. This replacement upper intake manifold fits the 1996 Blazer and includes a seal to ensure a proper vacuum seal between the manifold and the engine. The upper intake manifold sits on top of the engine and distributes intake air to the cylinders as part of the engine’s air intake system; replacing a damaged or worn unit with this part helps restore airflow and can help prevent vacuum leaks that can cause rough idle or power loss.
