Supertech Subaru EJ25 94mm Bore 0.051in (1.3mm) Thick MLS Head Gasket

This is a Supertech Multi-Layer Steel (MLS) head gasket specifically made for Subaru EJ25 engines with a 94mm bore. It's 0.051 inches (1.3mm) thick, which is a common thickness for rebuilding or modifying these engines. MLS gaskets are known for their durability and ability to handle higher cylinder pressures compared to older composite designs.

Using an MLS gasket like this one from Supertech is a solid choice when you're working on the top end of your Subaru EJ25. The multiple steel layers, along with specialized coatings, help create a strong seal between the cylinder head and the engine block. This is crucial for preventing coolant and oil leaks, and for maintaining proper compression, especially if you've done any performance upgrades or are simply replacing worn-out gaskets during a rebuild.

When installing this gasket, make sure your cylinder head and block surfaces are perfectly clean and flat. It's also important to use the correct torque sequence and values specified by the engine manufacturer or Supertech, as this ensures the gasket seals evenly and effectively.
