Cometic C4167-070 MLS Cylinder Head Gasket 78mm Bore .070" for Honda D15/D16

Cometic C4167-070 MLS Cylinder Head Gasket

The Cometic C4167-070 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for Honda D-series engines. This precision-manufactured gasket features a 78mm bore diameter and .070" (1.78mm) compressed thickness, providing an excellent balance of sealing performance and compression adjustment for modified engines.

Key Specifications

• Bore Diameter: 78mm
• Compressed Thickness: .070 inches
• Construction: Multi-Layer Steel (MLS)
• Material: Stainless steel layers with elastomeric coating

Compatible Engine Applications

This gasket is specifically designed for the following Honda D-series engine codes:

• D15Z1 - 1.5L VTEC-E
• D16Y5 - 1.6L VTEC-E
• D16Y7 - 1.6L SOHC
• D16Y8 - 1.6L VTEC
• D16Z6 - 1.6L VTEC

MLS Technology Benefits

Cometic's Multi-Layer Steel gaskets utilize multiple layers of stainless steel with an advanced coating system to provide superior sealing capabilities. The MLS design allows for optimal combustion sealing while accommodating the thermal expansion and contraction cycles of high-performance engines. The gasket's construction provides excellent recovery characteristics and maintains seal integrity even under extreme cylinder pressures associated with turbocharged or high-compression applications.

Performance Features

• Superior resistance to blown head gaskets compared to composite gaskets
• Excellent heat resistance and thermal conductivity
• Accommodates minor surface imperfections for reliable sealing
• Ideal for naturally aspirated, turbocharged, and supercharged applications
• Maintains compression integrity over extended periods

Note: Proper surface preparation is essential for MLS gasket installation. Cylinder head and block surfaces should have a smooth finish (typically 50 RA or smoother) and be free of imperfections. Follow manufacturer torque specifications and installation procedures for optimal results.
