Constructed from stainless steel with a folded stopper layer, each application features superior sealing compared to conventional multi layer steel gaskets. Additionally, Cosworth High Performance Head Gaskets are manufactured from pre-coated die cut stainless steel resulting in uniform coating distribution and consistent shape.   Subaru gaskets are sold as a pair (x2)     - 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 "folded stopper" sealing layer for additional torque around each cylinder. The width of sealing area is specific for each application thereby providing ultimate sealing properties. Please make sure to choose from the drop down menu whether you require the 04-07 STi style head gaskets, or the newer 2008+ STi style gaskets. 101mm Bore -- .78mm thickness OEM replacement size SKU: 200 Dimensions: 12X10X4 Weight: 2.00 Regular Price: $250.00  On Sale For: $220.00  Quantity:   Size 04-07 STi 08+ STi   101mm Bore -- 1.1mm thickness SKU: 200 Dimensions: 12X10X4 Weight: 3.00 Regular Price: $250.00  On Sale For: $220.00  Quantity:   Size 04-07 STi 08+ STi   101mm Bore -- 1.5mm thickness   04-07 Style suitable for lowering compression ratio when using EJ205 cylinder heads on EJ257 short block.
