Cometic C4495-027 MLS Cylinder Head Gasket Nissan Bore - RB20DE RB20DET 80mm

The Cometic C4495-027 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Nissan RB20DE and RB20DET engines. This precision-manufactured gasket features an 80mm bore diameter and .027" (0.69mm) compressed thickness, making it ideal for stock rebuilds or mild performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability
• 80mm bore diameter designed for RB20DE and RB20DET engine applications
• .027" compressed gasket thickness for proper compression ratio
• Embossed stainless steel layers with Viton rubber sealing beads
• Excellent rebound characteristics resist combustion pressure and thermal cycling
• Performs reliably in both naturally aspirated and turbocharged applications

Cometic MLS gaskets are constructed from multiple layers of stainless steel, with each layer serving a specific purpose in the sealing process. The result is a gasket that conforms to imperfect sealing surfaces while maintaining exceptional strength and resistance to blow-out. This gasket is compatible with Nissan RB20 engines commonly found in vehicles like the Nissan Skyline and other JDM platforms.
