Cometic C4580-030 MLS Cylinder Head Gasket for Nissan L28/L28E 89mm Bore

The Cometic C4580-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Nissan L28 and L28E inline-six engines. This precision gasket features an 89mm bore diameter and .030" (0.76mm) compressed thickness, making it ideal for street performance and turbocharged applications where increased clamp load and superior sealing are essential.

Key Features:

• Multi-Layer Steel construction provides superior sealing and durability under high-cylinder pressures
• 89mm bore diameter optimized for L28/L28E engines
• .030" compressed thickness for stock to mild performance builds
• Embossed stainless steel layers with Viton rubber coating resist coolant, oil, and combustion gases
• Increased clamp load tolerance reduces gasket failure in turbocharged and high-compression applications
• Re-torque capability allows for proper installation and gasket seating

Cometic MLS gaskets are manufactured using multiple layers of stainless steel with advanced coating technology, ensuring exceptional conformability to sealing surfaces while maintaining structural integrity. This gasket is a direct replacement for OEM gaskets and is compatible with both stock and performance-machined cylinder heads and blocks. Proper surface preparation (RA finish of 50-60 microinches recommended) is essential for optimal sealing performance.
