Head Gasket

The Cometic MLX Head Gasket is specifically engineered for use in B58turbocharged inline 6-cylinder engines found in various BMW chassis and the Toyota GR Supra A90/A91.

Gen 1 replaces BMW part # 11128654268 and #11128654269.

Gen 2 replaces Toyota part # 11115WAA04

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. 

It's important to note that MLS/MLX head gaskets are not compatible with engines that have O-rings or receiver grooves around the cylinder bores. These gaskets require smooth and flat surfaces to seal properly.
