Cometic C4320-066 MLS Cylinder Head Gasket for Nissan RB26DETT 87mm Bore

The Cometic C4320-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for the Nissan RB26DETT engine. This gasket features a precision 87mm bore diameter and a compressed thickness of .066 inches, making it ideal for both stock rebuilds and performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 87mm bore diameter designed specifically for RB26DETT applications
• .066 inch (1.68mm) compressed thickness
• Provides excellent torque retention and combustion sealing
• Resistant to extreme temperatures and pressures
• Accommodates engine movement and thermal expansion

Cometic's MLS gaskets use multiple layers of stainless steel with proprietary coatings to create a superior seal that withstands the extreme conditions found in high-performance engines. The gasket's design allows for slight movement between layers, which helps maintain consistent sealing pressure even as the engine block and cylinder head expand and contract during operation. This makes it an excellent choice for Nissan RB26DETT engines found in the R32, R33, and R34 Skyline GT-R models, particularly those running higher boost levels or modified setups.
