Cometic 03+ Subaru EJ255/04-10 EJ257 101mm .030 inch MLS Head Gasket

This is a single Multi-Layer Steel (MLS) head gasket from Cometic, designed for Subaru EJ255 and EJ257 engines. It features a 101mm bore and is machined .030 inches oversize, making it suitable for engine rebuilds where the cylinders have been bored out to this dimension. The outer layers of the gasket are embossed and coated with Viton, a material known for its resistance to heat and automotive fluids, helping to ensure a solid seal.

This gasket is built to handle the demands of these performance-oriented Subaru engines. The MLS construction offers excellent sealing capabilities, especially under high cylinder pressures. The .030 inch oversize bore means it's intended for engines that have been machined to match this larger diameter, ensuring proper piston-to-head clearance in a performance build.

This gasket fits a range of Subaru models like the Impreza, WRX STI, Forester, and Legacy, as well as the Saab 9-2X. Always confirm fitment for your specific vehicle and engine build.
