Intake manifold gaskets create a static seal between the intake manifold and the cylinder head, ensuring combustion chamber integrity. These gaskets are utilized in both gasoline and diesel engines, positioned between mating surfaces to prevent leaks of combustion gases, coolant, and oil. Common materials include composite multi-layer steel (MLS), rubber, or cork, selected for temperature resistance and sealing performance. Precise dimensional control and surface finish are critical to achieving a leak-free seal under high cylinder pressures and thermal cycling. Failure results in reduced engine efficiency, misfires, and potential component damage.
