The Cometic GM/Mercury Marine V8 1050 .051in MLS Intake Manifold Gasket Set - C5821-051 is a precision-engineered intake gasket with a compressed thickness of .051".
Cometic Multi-Layer Steel (MLS) intake gaskets provide a leak-proof seal between the intake manifold and cylinder head. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. A proper intake seal is critical for maintaining correct air-fuel mixture, vacuum, and coolant routing — making these gaskets essential for any engine build or intake upgrade.
