Product Details

The Cometic C14121-036 is a high-performance Multi-Layer Steel (MLX) cylinder head gasket engineered specifically for BMW B58B30M0 and B58B30M1 engines. This precision-manufactured gasket features an 83mm bore diameter and .036" compressed thickness, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel (MLX) construction for superior sealing and durability
  • 83mm bore diameter designed for BMW B58 engine applications
  • .036" (0.9mm) compressed thickness for precise compression control
  • Compatible with B58B30M0 and B58B30M1 engine variants
  • Engineered to withstand high cylinder pressures and temperatures
  • Stopper layer embossment for enhanced combustion sealing

Cometic MLX gaskets utilize multiple layers of stainless steel with a Viton rubber coating, creating a gasket that recovers and reseals better than traditional composite gaskets. The advanced design accommodates engine movement and thermal expansion while maintaining consistent clamping pressure across the sealing surface, making it ideal for both stock rebuilds and high-performance applications.
