This precision-manufactured gasket features an 84mm bore diameter and .051" (1.3mm) compressed thickness, providing an optimal balance of sealing capability and compression ratio adjustment.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing under high cylinder pressures
• 84mm bore diameter designed for Mazda BP-series engines
• .051" compressed thickness for precise compression control
• Engineered for turbocharged BP-4W and naturally aspirated BP-Z3 applications
• High-temperature resistant materials withstand extreme combustion temperatures
• Eliminates coolant and combustion gas leakage
• Ideal for performance builds, engine rebuilds, and forced induction upgrades

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that micro-seal imperfections in the sealing surface. This advanced design accommodates thermal expansion and cylinder pressure variations better than conventional composite gaskets, making it the preferred choice for high-performance and turbocharged applications. Perfect for Mazda Miata, Protege, and other BP-powered vehicles undergoing performance modifications or complete engine rebuilds.
