Cometic 03-11 Subaru EJ255 / 04-10 EJ257 Turbo 101mm Bore MLX Head Gasket

Starting with a compressed operating thickness of just 0.032 inches, this Cometic MLX head gasket is built for the specific demands of Subaru EJ255 and EJ257 turbocharged engines found in models like the Impreza, WRX STI, Forester, and Legacy. The Multi-Layer Stopper (MLX) design uses an integrated stopper layer to ensure a solid seal around the combustion chamber, even under high clamp loads, without causing distortion to the cylinder bore. This approach helps maintain the integrity of your engine's seal, crucial for turbocharged applications.

Cometic constructs these gaskets using multiple layers of stainless steel, with the outer layers treated to a Viton rubber coating. This combination offers good resistance and sealing properties. A notable benefit of this gasket design is that it requires no additional sealants during installation and does not need to be re-torqued after initial setup, simplifying the assembly process for your engine rebuild or repair.
