Cometic C4320-080 MLS Cylinder Head Gasket for Nissan RB26DETT 87mm Bore

The Cometic C4320-080 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for the Nissan RB26DETT engine. This gasket features an 87mm bore diameter and 0.080-inch thickness, providing precise sealing and compression control for modified and high-output applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 0.080-inch (2.0mm) compressed thickness for custom compression ratio tuning
• 87mm bore diameter designed for RB26DETT applications
• Multiple layers of stainless steel with elastomeric coating
• Excellent resistance to extreme cylinder pressures and temperatures
• Ideal for turbocharged and high-boost applications

Cometic MLS gaskets are constructed from multiple layers of stainless steel, which allow the gasket to conform to minor surface imperfections while maintaining superior combustion sealing. The embossed layers provide additional sealing around combustion chambers, oil passages, and coolant ports. This gasket is particularly well-suited for the demands of modified RB26DETT engines found in the Nissan Skyline GT-R, where increased boost levels and power output require upgraded head gasket solutions.
