This Cometic MLS Head Gasket is designed to replace BMW part numbers 11121721546, 11121721547, 11121721550, and 11121721551, specifically for the M40B16, M40B18, M42B18, and M44B19 engines.
Cometic MLS Gaskets are composed of multiple layers of stainless steel, the number of layers used varying by application.
These layers consist of both proprietary, high-temperature coated and uncoated stainless steel.
Additional layers increase active seal height and can be used to fine-tune compression.
The specialized coating used on Cometic Gaskets conforms to the surfaces of the cylinder head and engine block on the first heat cycle, creating a chemical bond.
MLS Gaskets are able to prevent blow-outs in engines with high cylinder pressure because the embossed layers act as a ‘spring’ and compensate for increased head lift.
