The Cometic Porsche M28.41/M28.42/M28.43/M28.44/M28.45 .080in MLS Cylinder Head Gasket-100mm Bore-RHS - C5780-080 is a precision-engineered head gasket with a 100mm bore and .080" compressed thickness for the Right-Hand Side (RHS).

The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
