Cometic 03+ Subaru EJ255/04-10 EJ257 101mm .075 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket starts with a .075 inch thickness and a 101mm bore, designed to seal the combustion chamber effectively in a wide range of vehicles. It’s built with multiple embossed layers of stainless steel, giving it increased strength and the ability to rebound, which helps resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a solid seal even under demanding conditions. This construction means the gasket doesn't require any additional sealants, making installation more straightforward.

MLS gaskets are a popular choice for high-output engines because they can handle the shearing forces that can occur between aluminum heads and cast iron blocks, or between two aluminum components. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .075 inch on this particular gasket. This makes it a well-built option for applications like the Subaru EJ255 and EJ257 engines, as well as for many Toyota trucks and SUVs including the 4Runner, Tacoma, and Tundra.
