MLS Head Gasket

This Cometic MLS Head Gasket is engineered to replace BMW part numbers 11121316705, 11121307529, and 11121401351 for the S38B35, S38B36, and S38B38 engines. Preferred in high-performance builds, MLS (Multi-Layer Steel) gaskets provide maximum durability and resistance to shearing and bore distortion.

Key Benefits:

• Multi-layer stainless steel construction for superior durability.
• No additional sealant required for installation.
  

Cut-Ring Head Gasket

The Cut-Ring Head Gasket is an advanced sealing solution for S38B35, S38B36, and S38B38 engines in E24, E28, and E34 M5/M6 chassis. Unlike MLS gaskets, Cut-Ring gaskets feature stainless steel rings that bite into the cylinder head upon installation, creating an extremely strong combustion seal—ideal for high-boost and high-compression applications.

Key Benefits:

• Superior sealing strength for high-horsepower, turbocharged, and supercharged setups.
• Eliminates the need for O-ringing the block while maintaining excellent combustion chamber sealing.

Installation Notes:

• Engine block and head surfaces must be clean and properly prepared for the rings to seat correctly.
• Follow proper torque sequence and specifications when installing head studs or bolts.
