The Cometic Mazda Miata 1.6L 80mm .066 inch MLS-5 Head Gasket B6D Motor - C4122-066 is a precision-engineered head gasket with a 80mm bore and .066" compressed thickness.
The Cometic 5-Layer Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring 5-Layer Multi-Layer Steel (MLS) construction, this gasket uses five embossed steel layers delivering exceptional clamping load distribution for high-output applications. 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.
Verified fitment: Mazda 323 (1988–1993); Mazda MX 3 (1992–1993); Mazda Miata (1990–1993); Mercury Capri (1991–1994).
