Cometic C4189-070 MLS Cylinder Head Gasket Bore Thickness - 83mm 070

The Cometic C4189-070 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for Honda B-series engines. This precision-manufactured gasket features an 83mm bore diameter and .070" (1.78mm) compressed thickness, designed to provide superior sealing under high-combustion pressures and extreme temperatures.

Key Features:

• Multi-Layer Steel construction for maximum durability and heat resistance
• 83mm bore diameter optimized for B-series engine applications
• .070" compressed thickness for precise compression ratio tuning
• Advanced coating technology ensures superior sealing and prevents corrosion
• Eliminates gasket failure common with stock composite gaskets in high-performance applications
• Compatible with Honda B16A2, B16A3, B17A1, B18C1, and B18C5 engines

Cometic MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to withstand the extreme conditions of turbocharged, supercharged, and high-compression naturally aspirated engines. The embossed layers provide multiple sealing points that adapt to block and head surface imperfections while maintaining consistent clamping pressure across the entire sealing surface.

Ideal for engine builders, tuners, and performance enthusiasts seeking reliable head gasket sealing for street, track, or racing applications. Professional installation with proper surface preparation and torque specifications is recommended for optimal performance.
