The Cometic Ford 5.0L Gen-3 Coyote Modular V8 94.5mm Bore LHS .040in MLX Cylinder Head Gasket - C15549-040 is a precision-engineered head gasket with a 94.5mm bore and .040" compressed thickness for the Left-Hand Side (LHS).
The Cometic MLX Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring MLX Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers for superior sealing under extreme cylinder pressures and temperatures. 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.
