Cometic C4237-051 Honda B Series VTEC Head Gasket Bore MLS - 81mm 051

The Cometic C4237-051 is a Multi-Layer Steel (MLS) cylinder head gasket specifically engineered for Honda B Series hybrid engine builds using a VTEC cylinder head with a non-VTEC block. This .051" thick gasket features an 81mm bore diameter and provides exceptional sealing performance for turbocharged and high-compression applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and reliability
• .051" (1.30mm) compressed thickness for precise compression ratio tuning
• 81mm bore diameter optimized for Honda B Series engines
• Designed specifically for VTEC head to non-VTEC block hybrid configurations
• Eliminates the need for OEM gaskets in performance builds
• Excellent resistance to extreme temperatures and pressures
• Accommodates minor surface imperfections for reliable sealing

Cometic MLS gaskets feature multiple layers of stainless steel with embossed sealing beads that provide even clamping pressure across the sealing surface. This design allows the gasket to recover and maintain seal integrity through repeated heat cycles, making it ideal for turbocharged, supercharged, and naturally aspirated performance applications. Perfect for B18C head on B18A/B or B20 block swaps commonly found in Honda Civic, Integra, and CRX builds.
