Intake Manifold Assembly

The ACDelco 12638038 Intake Manifold Assembly is a GM Original Equipment component designed to ensure optimal engine performance. It precisely distributes incoming air to each intake port within the cylinder head, facilitating the correct air-fuel mixture essential for combustion. Manufactured from durable Nylon and finished in Black, this intake manifold is built to meet the same stringent specifications for fit, form, and function as the original part it replaces. As a GM-recommended component, it offers the expected quality, reliability, and service life from General Motors. This intake manifold assembly is compatible with a wide range of GM vehicles from 2010 to 2017, including Chevrolet Express vans, Chevrolet Silverado and Tahoe models, GMC Savana vans, GMC Sierra and Yukon models, and Cadillac Escalade. Please verify fitment with your specific vehicle's year, make, and model. Installation requires careful attention to manufacturer's specifications, particularly regarding torque sequence and values for intake bolts, to prevent overtightening and potential damage. Proper maintenance, including keeping the air duct assembly clean and the engine air filter changed, is crucial for optimal function and longevity.
