Cometic C4181-030 MLS Cylinder Head Gasket for Honda B18A1/B18B1 83mm Bore

The Cometic C4181-030 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Honda B18A1 and B18B1 engines. This gasket features an 83mm bore diameter and a compressed thickness of .030 inches, making it ideal for stock and mildly modified engine applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability
• .030-inch compressed thickness for precise compression ratio tuning
• 83mm bore diameter designed for B18A1 and B18B1 engine blocks
• Exceeds OEM specifications for reliability and performance
• Accommodates thermal expansion and contraction better than composite gaskets
• Resists coolant and oil leakage under high-temperature conditions

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to create a micro-seal that conforms to the block and cylinder head surfaces. This design eliminates the need for sealants and provides consistent clamping pressure across the entire sealing surface. The .030-inch thickness allows engine builders to fine-tune compression ratios while maintaining proper piston-to-valve clearance. Compatible with Honda Integra LS and other vehicles equipped with B18A1 or B18B1 non-VTEC engines.
