The Cometic C4189-080 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for Honda B-series engines. This precision gasket features an 83mm bore diameter and .080" (2.0mm) compressed thickness, designed specifically for B16A2, B16A3, B17A1, B18C1, and B18C5 applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high cylinder pressures
• 83mm bore diameter accommodates stock and mild performance builds
• .080" compressed thickness allows for precise compression ratio tuning
• Embossed stainless steel layers with viton rubber coating ensure excellent resistance to combustion gases and coolant
• Engineered to withstand extreme temperatures and pressures in forced induction and high-compression applications
• Requires proper surface preparation: surfaces should be smooth with RA finish of 50-60 for optimal sealing

Cometic MLS gaskets are a proven choice for Honda performance enthusiasts seeking reliable head sealing for street, track, and boosted applications. The layered steel design allows for minor surface imperfections while maintaining superior combustion sealing compared to traditional composite gaskets.
