Cometic Subaru EJ255 Version 2 - 2007-2018 EJ257 .120in MLS Cylinder Head Gasket - 101mm Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer coating of Viton rubber. This design is crucial for sealing the combustion chamber effectively, especially in high-output engines where pressures are significantly higher than stock. The compressed operating thickness is 0.036 inches, and it's designed for a 101mm bore, making it suitable for Subaru EJ255 Version 2 and EJ257 engines from 2007 through 2018, as well as fitting other vehicles like the Saab 9-2X, Subaru Baja, Forester, Impreza, Legacy, and Outback.

The strength of MLS gaskets comes from their layered stainless steel construction, which allows them to rebound and resist corrosion. This makes them ideal for applications using aluminum heads with either aluminum or cast iron blocks, as they can handle the shearing forces that arise from the different expansion rates of these materials. The Viton coating on the outer layers is a heat-resistant elastomer that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal in demanding conditions without the need for additional sealants.
