Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and durability
• 85mm bore diameter for optimal combustion chamber sealing
• .084" (2.13mm) compressed thickness
• Engineered for BMW M50 and M52 series engines including M50TUB24, M50B25, M50TUB25, M52TUB24, M52B25, M52TUB25, M52B28, and M52TUB28
• Advanced coating technology prevents corrosion and improves torque retention
• Designed to handle higher cylinder pressures than OEM gaskets
• Maintains proper sealing in high-temperature and high-compression environments

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to create a superior seal that conforms to irregular sealing surfaces. The spring-like properties of MLS gaskets allow them to recover and maintain clamping force under extreme conditions, making them ideal for performance builds, forced induction applications, and engine rebuilds where reliability is critical.
