Cometic Multi-layer Steel Head Gasket Set, BMW N63/S63

The Cometic MLX Head Gasket is designed to replace BMW part numbers 11127567764 and 11127567765, specifically for the N63 and S63 engines found in F10/F11/F12/F13/F15/F16/F01/F02 chassis.

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.

This layer provides a torque limiting surface that prevents yielding of the combustion seal.
