The Cometic Nissan VK566DE 5.6L 100mm Bore .040 inch MLS Head Gasket - Right - C4923-040 is a precision-engineered head gasket with a 100mm bore and .040" 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.
