Cometic Multi-layer Steel Head Gasket, BMW B58 Gen1

The Cometic MLX Head Gasket is specifically engineered for use in B58 Gen 1 turbocharged inline 6-cylinder engines found in various BMW chassis and the Toyota GR Supra A90/A91.

Gen 1 replaces BMW part # 11128654268 and #11128654269.

C14144-036 Composed of multiple layers of embossed coated and uncoated stainless steel, MLX gaskets are specially designed to conform to the surfaces of the cylinder head and engine block on the first heat cycle, creating a chemical bond via Cometic's proprietary coatings.

These coatings provide a micro-seal for fluids against the head and block surface.

The layers of the MLX gasket act as a spring, protecting against blowout and increasing active seal height by compensating for increased head lift.

MLX Head Gaskets are different from MLS because they feature an extra,specialized 'stopper' fold-over layer.
