ACDelco GM Original Equipment Engine Intake Manifold Gasket Sets include everything required to replace your vehicle's engine intake manifold gasket. The engine intake manifold gasket seals the intake manifold to the cylinder head intake ports. It prevents the loss of fuel/air mixture from the intake manifold and prevents dirt/debris from entering into the engine and intake ports. These engine intake manifold gasket sets feature high-grade rubber gaskets, come with the appropriate manifold bolts that must be changed when the manifold gasket is changed, and are GM-recommended replacements for your vehicle's original components. These original equipment kits have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
