MLS or Cooper ?

Head gaskets from the MLS range (Multi Layer Steel) provide a superior sealing to OEM, and offer a wide choice of thicknesses and diameters, suitable for all needs. They are made of several layers of first quality, shape-memory stainless steel (2 to 5 layers depending on the application), to guarantee the best durability against high compression ratios and boost. They benefit from reinforcements around coolant and oil holes. A specific coating is applied to the external layers for a uniform seal, even in the presence of small surface imperfections. To finish with, Gas Stopper technology helps to reduce long term deformation of the material.

Cooper Ring head gaskets are particularly suitable for heavily supercharged and turbocharged applications (more than 2 bars of boost, N2O use, extreme N/A compression ratios…). They are made from a high performance asbestos-free composite, non-organic materials, aramid fibers and elastomer. They benefit from silicone reinforcements in critical areas and special coating for uniform sealing. Theses gaskets come with stainless steel separated rings (“Cooper Rings”), ensuring better tightness between the block and the cylinder head. These products are ready-to-use and do not require block or head grinding.

Please note : the above application list is non-exhaustive, you can double check compatibility and all applications using manufacturer database before ordering your head gasket.
