What is a Multi-Layer Steel (MLS) head gasket?

An MLS head gasket uses several layers of stainless steel to create a strong and durable seal between the cylinder head and engine block. This construction helps it handle high pressures and temperatures better than older gasket types.

What does the .040in thickness mean for my engine?

The .040 inch thickness refers to the gasket's compressed height. This specific thickness is important for maintaining the correct compression ratio and valve-to-piston clearance in your 5.0L Coyote engine.

Does this gasket come with any hardware?

This product is for the left-side head gasket only and does not include installation hardware. It is recommended to refer to the manufacturer's installation instructions for any additional parts or hardware needed for proper installation.

About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's specifically made for the 2018 Ford Mustang's 5.0L Gen-3 Coyote Modular V8 engine, featuring a 94.5mm bore and a .040 inch thickness. This gasket is designed to handle the tough conditions found in modern V8 engines, ensuring a solid seal between your cylinder head and engine block.

This gasket uses multiple layers of stainless steel, which gives it strength and helps it resist corrosion and rebound under pressure. The outer layers are coated on both sides with Viton, a material that can handle high temperatures up to 482°F (250°C) and works well in various sealing environments and surface conditions. This updated coating helps maintain a strong seal even when the engine is working hard.
