Cometic 03+ Subaru EJ255/04-10 EJ257 101mm .066 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.036 inches, using multiple embossed layers of stainless steel. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments and various surface finishes. This gasket is designed to provide maximum sealing performance for high-output engines and is ideal for applications using aluminum heads with either aluminum or cast iron blocks, as it can withstand the shearing forces between different metals.

The center layer of this gasket is uncoated stainless steel, allowing for variations in thickness to meet different requirements, like this specific 0.066-inch version with a 101mm bore. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation. The multiple stainless steel layers not only add strength but also provide rebound resistance and help prevent corrosion. This gasket fits a range of Subaru models, including the Impreza, Forester, and Legacy, from the mid-2000s through the mid-2010s.
