Tomei RB25DET Head Gasket 87.0 Bore

TOMEI GASKET: Highly resistant to heat and extremely durable.Superior sealing that can withstand high power applications. Thicker seals around the bore keeps pressurized gasses within the combustion chamber. Thicker bore seals usually results in weaker seals around the oil and water routes. However, TOMEI gaskets have been specially designed to distributed pressure evenly in order to maintain a high quality seal across the entire surface. Each gasket features an optimized combination of seals and beads derived from analyzing the engine's individual characteristics that include bore spacing/layout, head/block materials and sealing properties. This also helps limit the head/warp distortion that's often associated with other high performance gaskets. Stainless steel is used across all our high performance gaskets. Robust and resistant to high temperatures,stainless steel facilitates efficient transfer of heat from the combustion chamber to the cylinder block. In addition, it's flexible nature further strengthens the seal made by the spring-like beads which helps prevent issues such as blown gaskets and melted cylinder blocks. UNIQUE RUBBER COATING Both the top and bottom layers of the gaskets are coated in a specially developed unique rubber coating that reinforces the seal and contact with the head/block surfaces.
