Cometic C4566-051 MLS Cylinder Head Gasket Bore Honda - 83mm B20A3/B20A5

The Cometic C4566-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Honda B20A3 and B20A5 engines. This gasket features a .051-inch (1.3mm) compressed thickness and an 83mm bore diameter, providing a precise seal between the cylinder head and engine block.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and durability
• .051-inch compressed thickness for optimal sealing performance
• 83mm bore diameter designed for Honda B20A3 and B20A5 applications
• Advanced material composition resists corrosion and extreme temperatures
• Provides excellent resistance to combustion pressure and coolant seepage
• Ideal for stock rebuilds and performance applications

Cometic MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that can withstand extreme cylinder pressures while maintaining the critical seal between the cylinder head and block. The layered design allows the gasket to move with the engine's thermal expansion and contraction, preventing gasket failure and maintaining consistent sealing throughout the engine's operating range.
