Cometic C4580-098 MLS Cylinder Head Gasket for Nissan L28/L28E 89mm Bore

The Cometic C4580-098 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Nissan L28 and L28E inline-six engines. This precision-manufactured gasket features a .098-inch (2.5mm) 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 cylinder pressures
• 89mm bore diameter accommodates stock and slightly overbored L28/L28E engines
• .098-inch compressed thickness allows for fine-tuning compression ratios
• Advanced embossment design ensures even pressure distribution across the sealing surface
• Engineered to withstand extreme temperatures and combustion pressures
• Does not require additional sealants when used with proper surface preparation

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that provide excellent conformability to sealing surfaces. This design makes them more forgiving than traditional solid copper or composite gaskets, while still maintaining exceptional durability in high-performance and forced-induction applications. Proper deck surface preparation (RA finish of 50-60 recommended) is essential for optimal sealing performance.
