Cosworth Head Gasket 101.3mm Bore 1.1mm Subaru STI 2008-2019
Designed specifically for the STi motors, these gaskets feature several slight changes that the previous 04-06 STI motors did not have. Cosworth High Performance Multi layer steel head gaskets are designed to seal in power under the most demanding conditions. Each gasket is carefully engineered with the following.
- 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.
