Cosworth high performance head gaskets for the Nissan Skyline RB25 & RB25DET NEO are constructed from stainless steel with a folded stopper layer and engineered to seal in power under the most demanding conditions.
Each application features superior sealing compared to conventional metal multi layer steel gaskets. Additionally, Cosworth High Performance Head Gaskets are manufactured from pre-coated die cut stainless steel resulting in unifom coating distribution and consistent shape.
Each gasket is carefully engineered with the following 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 nitrite rubber ensures consistent distribution of coating with no high or low areas.
* Manufacturing dimensional tolerance of +/- 0.0001"
* Die cut manufacturing process ensures smooth edges, unlike laser cut gaskets.
* Cosworth gaskets feature a "folded stopper" layer for additional clamping force around each cylinder. The width of the sealing area is specific for each application thereby providing ultimate sealing properties.
