Cometic Subaru EJ255 Version 2 2007-2018 EJ257 100mm Bore 0.040in MLS Cylinder Head Gasket

This listing is for a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Subaru EJ255 Version 2 and EJ257 engines. It features a 100mm bore and a thickness of 0.040 inches, making it suitable for specific engine builds and modifications.

MLS head gaskets are known for their strength and ability to handle higher cylinder pressures compared to traditional composite gaskets. This design uses multiple layers of stainless steel with a specialized coating to create a strong seal between the cylinder head and the engine block. The 0.040 inch thickness is a specific dimension that can affect compression ratio, so it's important to consider this when planning your engine build.

When installing this gasket, ensure both the cylinder head and the block surface are perfectly clean and flat. Always refer to the manufacturer's installation instructions for proper torque sequences and specifications, as these are critical for achieving a reliable seal with MLS gaskets.
