Cometic C4180-040 MLS Cylinder Head Gasket Bore Honda - 84mm B18A1/B18B1

The Cometic C4180-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Honda B18A1 and B18B1 engines. This precision-manufactured gasket features an 84mm bore diameter and a compressed thickness of .040 inches (1.0mm), making it ideal for stock or mildly modified engine builds.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability
• 84mm bore diameter designed for B18A1 and B18B1 applications
• .040" (1.0mm) compressed thickness for precise compression control
• Exceeds OEM specifications for reliability and performance
• Engineered to withstand high cylinder pressures and temperatures
• Eliminates gasket failure and head lifting common with stock gaskets

Cometic MLS gaskets feature multiple layers of stainless steel with an elastomeric coating that provides exceptional recovery and sealing characteristics. The embossed active sealing area ensures maximum combustion seal while the stopper layer controls gasket thickness and provides robust armor around the combustion chamber. This gasket is manufactured using advanced materials and processes that make it far superior to traditional composite head gaskets, especially in performance and forced induction applications.

Application: Honda B18A1 and B18B1 engines (commonly found in 1990-2001 Acura Integra LS, RS, GS models and 1994-1997 Honda CR-V)
