Product Details

The Cometic C4352-140 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW M54B25 and M54B30 engines. This performance gasket features a compressed thickness of 0.140 inches and an 85mm bore diameter, providing exceptional sealing capabilities for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 0.140-inch compressed thickness allows for precise compression ratio tuning
  • 85mm bore diameter designed for BMW M54B25 2.5L and M54B30 3.0L inline-six engines
  • Exceeds OEM specifications for performance and reliability
  • Ideal for turbocharged, supercharged, and high-compression builds
  • Advanced coating technology prevents corrosion and ensures optimal seal

Cometic's MLS gaskets feature multiple layers of stainless steel with proprietary coatings that accommodate engine movement and thermal expansion while maintaining a secure seal. This gasket is the preferred choice for BMW enthusiasts building engines for street performance, track use, or forced induction applications where OEM gaskets may fail under increased cylinder pressures.
