Intake Manifold & Related

Browse New OEM intake manifold assemblies and related components for GM vehicles. Our factory-original intake manifolds are sourced from GM surplus — the correct port configuration, gasket surface profile, and sensor port locations for your specific engine.

The intake manifold defines the air distribution and plenum volume characteristics of your engine's induction system. OEM manifolds maintain the factory port velocity, runner length, and tumble characteristics engineered for your engine's power and efficiency targets.

Intake manifold replacement requires proper cleaning of gasket surfaces and careful torque sequencing. Inspect throttle body, MAP sensor, and PCV system components at the same time. Verify part numbers against your engine RPO code before ordering.
