Cometic C14141-040 MLX Cylinder Head Gasket for Porsche - 996

The Cometic C14141-040 is a precision-engineered MLX (Multi-Layer-Xtreme) cylinder head gasket designed specifically for Porsche 996 engines with M96.70, M96.70S, M96.70SL, M96.76, and M96.79 engine codes. This high-performance gasket features a .040-inch compressed thickness and 103.5mm bore diameter, providing exceptional sealing performance for both street and performance applications.

MLX Technology Advantages:

• Multi-layer stainless steel construction with integrated stopper layer for superior combustion chamber sealing
• Enhanced clamp load distribution around the cylinder bore without increasing bore distortion
• Multiple embossed layers with heat-resistant fluoroelastomer coating rated to 482°F (250°C)
• Three-layer design combining strength, rebound capability, and corrosion resistance
• No sealants or re-torquing required after installation

Construction Details:

• Material: MLX (Multi-Layer-Xtreme) stainless steel
• Compressed thickness: .040 inch
• Bore size: 103.5mm (round bore shape)
• Number of layers: 3
• UPC: 191070555467

Cometic MLX gaskets represent advanced gasket technology, using the same high-quality materials as their MLS gaskets but featuring an additional fold-over stopper layer that provides a torque-limiting surface preventing yielding of the combustion seal. The embossed outer layers meet the demanding requirements of harsh sealing conditions while conforming to various load distributions and mounting surfaces. Ideal for both aluminum-to-aluminum and aluminum-to-cast iron applications, this gasket withstands the shearing forces created between dissimilar materials in high-performance Porsche flat-six engines.
