About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built for the 2014+ Subaru FA20F engine, specifically for the left side. It features an 89.5mm bore and a compressed operating thickness of 0.036 inches, with an initial thickness of 0.040 inches. MLS gaskets are a solid choice for high-output engines because they offer excellent sealing without needing additional sealants, and they handle the stresses between aluminum heads and cast iron blocks well.

The construction uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments. The center layer is uncoated stainless steel, which can be varied to achieve different thicknesses, like the 0.040 inches found in this gasket.
