Cosworth Mitsubishi EVO IX 4G63 metal head gasket is a high performance
gasket designed to seal under high power under the most demanding
conditions. Cosworth's Mitsubishi EVO IX 4G63 head gasket is available
in 86mm bore with a variety of thicknesses. Each Cosworth Mitsubishi
EVO 4G63 headgasket features:
Individual die cut layers of stainless steel with superior consistency compared to laser cut gaskets.
Pre-coated stainless steel with a 0.25 micron layer of nitrile rubber
ensures consistent distribution of coating with no high or low areas.
Manufacturing dimensional tolerance of 0.002”.
Die cut manufacturing process ensures smooth edges, unlike laser cut gaskets.
Cosworth gaskets feature a “stopper” sealing layer for additional
torque around each cylinder. The width of sealing area is specific for
each application thereby providing ultimate sealing properties.
