Cometic C4580-140 MLS Cylinder Head Gasket for Nissan L28/L28E 89mm Bore

The Cometic C4580-140 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Nissan L28 and L28E inline-six engines. This precision-engineered gasket features a .140" (3.6mm) compressed thickness and an 89mm bore diameter, making it ideal for both stock rebuilds and performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high combustion pressures
• .140" compressed thickness allows for precise compression ratio tuning
• 89mm bore diameter optimized for L28 and L28E engine specifications
• Stainless steel construction with advanced coating technology prevents corrosion and ensures reliable sealing
• Designed to handle extreme temperature cycling and high-performance applications
• Reusable design allows for multiple installations when properly maintained

Cometic MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that conforms to irregular sealing surfaces while maintaining excellent recovery properties. This design is particularly beneficial for turbocharged, supercharged, or high-compression naturally aspirated engines where cylinder head movement and extreme temperatures are concerns. Compatible with Datsun/Nissan 280Z, 280ZX, and other vehicles equipped with L28 or L28E engines.
