Cometic C4983-030 MLS Cylinder Head Gasket Bore Mazda BP Engine - 84mm 030

The Cometic C4983-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Mazda BP-4W Turbo and BP-Z3 engines. This precision gasket features an 84mm bore diameter and .030" (0.76mm) compressed thickness, providing exceptional sealing performance for both stock and modified applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and durability
• 84mm bore diameter designed for Mazda BP-4W Turbo and BP-Z3 engines
• .030" compressed thickness for precise compression ratio tuning
• Excellent resistance to combustion pressure and thermal cycling
• Eliminates the need for additional sealants with advanced embossment technology
• Ideal for turbocharged and high-performance builds requiring reliable sealing

Cometic MLS gaskets utilize multiple layers of stainless steel with elastomeric coatings that recover quickly from thermal expansion and contraction. This design makes them particularly effective in turbocharged applications where elevated combustion temperatures and pressures demand maximum gasket reliability. The .030" thickness allows engine builders to fine-tune compression ratios when building or rebuilding Mazda BP engines commonly found in Miata, Protege, and Familia GT applications.
