TOMEI SUBARU IMPREZA EJ25 WRX STI METAL HEAD GASKET 101MM BORE 1.2MM:

Tomei selected stainless for the material of the gasket, which it is possible to cool down the cylinder effectively by transferring heat to the cylinder head equally with the high thermal conductivity of stainless. And since it does not become high temperature locally, cylinder head will hardly blow. Since intensity of stainless steel is high, it can make the joint rigidity of the cylinder head and the engine block high and prevents blown head. If combination of a head and a block is firm, twist and bent of the whole engine can be reduced while rigidity is increased, and the durability of power transmission will be improved.

■	Super Grommet Design The factory type is made from metal but the design is the bead type which is not as effective in sealing as the super grommet design. Most aftermarket metal gaskets are of the grommet design which is better but the TOMEI Super Grommet design gives you the highest sealing efficiency possible and increased durability. (Super Grommet=Dual Sealing System from bead structure and metal grommet)
■	Custom Rib Design (Improved Seal Around the Water Gallerie) With each model change from Subaru engineers the improved engine design from the GC8 to GDB and A models had the increased the rib of the outer bore diameter which improved the gas sealing characteristics. But the results of that change made the water and oil galleries seal decrease. So when the power is increased there is also the increased possibility for oil and water leaks to occur. TOMEI engineers has a second look at the design of the rib height and the Super Grommet Design and we have achieved an overall improvement in overall seal.
■	Various Sizes Available We had made 2 types of thickness available for the better option for you to achieve your desired compression ratio for your application. Now you can build an engine with higher accuracy to suit your needs.
