Manifold – Gm (25534413)

Manifold handles exhaust gas or intake charge. On emissions-controlled components, the part must match the engine calibration, not just the pipe diameter.

Replace the Manifold when exhaust leaks at a flange, when flow is restricted, or when the internal core has broken up and rattles at idle. Confirm that the engine is not running rich before fitting a new one.

This Manifold is listed as part 25534413 (Throttle Bodies & Intake). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.
