Cometic C4512-066 MLS Cylinder Head Gasket for Opel CIH Bore - 20E/20N/20S 97mm

The Cometic C4512-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Opel 20E, 20N, and 20S CIH engines. This precision-manufactured gasket features a 97mm bore diameter and .066" compressed thickness, providing superior sealing performance for both stock and modified applications.

Key Features:

• Multi-Layer Steel (MLS) construction for maximum durability and heat resistance
• 97mm bore diameter designed for Opel CIH engine specifications
• .066" (1.68mm) compressed thickness for precise combustion chamber sealing
• Superior torque retention compared to traditional composite gaskets
• Excellent rebound characteristics accommodate thermal expansion and contraction
• Ideal for turbocharged, supercharged, and high-compression applications

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to create a superior seal that withstands extreme cylinder pressures and temperatures. The embossed design ensures proper load distribution across the sealing surface, while the steel construction eliminates the need for retorquing that composite gaskets often require.
