Cometic C4566-045 MLS Cylinder Head Gasket for Honda B20A3/B20A5 83mm Bore

The Cometic C4566-045 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Honda B20A3 and B20A5 engines. This high-performance gasket features an 83mm bore diameter and a compressed thickness of .045 inches, making it ideal for both stock rebuilds and modified applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 83mm bore diameter engineered for Honda B20A3/B20A5 engines
• .045" (0.045 inch) compressed gasket thickness
• Precision manufacturing ensures consistent compression and optimal sealing
• Handles high cylinder pressures in both naturally aspirated and forced induction applications
• Resists gasket failure from extreme temperatures and combustion pressures

Cometic MLS head gaskets are constructed from multiple layers of stainless steel, with each layer serving a specific purpose to create a superior seal between the engine block and cylinder head. The embossed layers provide micro-sealing around combustion chambers, coolant passages, and oil return holes, while the outer layers add strength and stability. This design allows the gasket to withstand the movement and thermal expansion that occurs during engine operation, making it an excellent choice for high-performance Honda B-series engine builds.
