The Cometic Ford 2.3L 4CYL 3.94in Bore .051 inch MLS Head Gasket - C5709-051 is a precision-engineered head gasket with a 100mm bore and .94" compressed thickness.

The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short.

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.
