What is the advantage of using a Multi-Layer Steel (MLS) head gasket?

MLS gaskets are made from multiple layers of stainless steel, which offers increased strength and better resistance to corrosion compared to older gasket materials. They also have good rebound characteristics to maintain a seal under varying engine conditions.

What does the Viton coating do on this gasket?

The Viton rubber coating on both sides of the gasket helps it meet the demands of harsh sealing environments and varying surface finishes. It's specifically heat resistant up to 482°F (250°C), which is important for maintaining a seal under high temperatures.

Does this gasket come with any hardware?

This product listing is for the Cometic head gasket only. It does not include head bolts or other installation hardware, which should be sourced separately if needed.

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with three to five layers of stainless steel, chosen for its strength and resistance to corrosion. The .070 inch thickness and 90mm bore are specific dimensions for certain Subaru EZ30D mk II engines, and this is the Left Hand Side (LHS) gasket. It's designed to handle tough sealing jobs across a range of vehicles, including models like the Subaru Outback, Legacy, and Mazda Miata.

The outer layers of this gasket are embossed and then coated on both sides with Viton, a high-performance rubber material.
