About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer coating of Viton rubber on both sides. When compressed, it measures 0.036 inches thick, but it starts at 0.086 inches to accommodate various engine builds. This construction is designed to handle the high output demands of modern engines and is suitable for mating aluminum heads to either aluminum or cast iron blocks, resisting the shearing forces that can occur between different metals.

The stainless steel layers provide increased strength and the ability to rebound, while also resisting corrosion. The Viton coating, a heat-resistant material capable of withstanding up to 482°F (250°C), is applied to the outer layers to ensure a reliable seal in demanding conditions. The center layer is uncoated stainless steel, allowing for variations in thickness to meet specific engine requirements. These MLS gaskets are designed to provide maximum sealing performance without the need for additional sealants.

This gasket is a solid option for Subaru Impreza owners looking for a well-built head gasket that can handle increased engine output. It fits a range of Subaru models including the Impreza, Forester, Legacy, Outback, and Baja, making it a versatile choice for many Subaru builds.
