Cometic Jaguar 1973-1992 4.2L XK6 .036in MLS Cylinder Head Gasket - 3.690in Bore - C4127-036

The Cometic Jaguar 1973-1992 4.2L XK6 .036in MLS Cylinder Head Gasket - 3.690in Bore - C4127-036 is a precision-engineered head gasket with a 3.690" bore and .036" 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.
