Cometic Nissan E13S/E15ET/E15S/E16i/E16S/E16ST .045in MLS Cylinder Head Gasket - 77mm Bore - C4178-045

The Cometic Nissan E13S/E15ET/E15S/E16i/E16S/E16ST .045in MLS Cylinder Head Gasket - 77mm Bore - C4178-045 is a precision-engineered head gasket with a 77mm bore and .045" compressed thickness.

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.
