Cometic C4528-045 BMW MLS Cylinder Head Gasket Bore - S85B50 93mm 0.045

The Cometic C4528-045 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for the BMW S85B50 V10 engine. This precision-manufactured gasket features a 93mm bore diameter and 0.045-inch compressed thickness, designed to provide superior sealing under extreme cylinder pressures and temperatures.

Key Features:

• Multi-Layer Steel (MLS) construction for maximum durability and reliability
• 93mm bore diameter optimized for BMW S85B50 V10 engine specifications
• 0.045-inch (1.14mm) compressed thickness for precise compression ratio control
• Advanced embossment design ensures even pressure distribution across sealing surfaces
• Accommodates thermal expansion and minor surface imperfections
• Superior resistance to blow-out and coolant leaks

Cometic MLS gaskets are constructed with multiple layers of stainless steel, featuring a proprietary coating that enhances the micro-seal between layers. This design allows the gasket to rebound and maintain consistent clamping pressure across a wide range of temperatures, making it ideal for both high-performance street applications and racing environments. The gasket's ability to conform to slight surface irregularities provides a reliable seal even on resurfaced or aftermarket cylinder heads.
