Product Description

The Cometic C4568-060 is a premium Multi-Layer Steel head gasket designed specifically for the Mazda BP-4W / BP-ZE 1.8L DOHC engines used in the Miata (1994-1997, 1999-2000) and Protege (1990-1998). With an increased compressed thickness of **0.060"** and a bore of **84 mm**, this gasket is ideal for rebuilds where extra deck height spacing is required due to machining or head-surface modifications. The outer Viton coatings provide excellent resistance to coolant, oil, and combustion exposure under high temperature and pressure.

This gasket is perfect for builds that push the stock limits, such as mild forced induction, high compression, or aggressive tuning, where sealing reliability is critical. Before purchasing, ensure your engine is the DOHC 1.8L BP-series and that the head and block mating surfaces are flat, clean, and within spec. Torque using the factory or upgraded hardware sequence. Fitment confirmed through 2000; **2025 unconfirmed** for later BP-series variants.
