Cometic Gasket is the world leader in custom multi-layer steel head gaskets for performance and motorsport engines. From off-the-shelf MLS for popular platforms to bespoke gaskets for race-only builds, Cometic seals everything from Honda B-series to LSX.
When building a high-output Subaru EJ20 engine, the head gasket is the most critical component for maintaining cylinder pressure. The Cometic .040 MLS (Multi-Layer Steel) Head Gasket is engineered to provide an uncompromising seal under extreme boost and thermal stress. Designed specifically for the 93mm bore of the EJ20GN, this gasket eliminates the need for additional sealants, ensuring a clean, reliable installation.
This gasket utilizes multiple layers of stainless steel to provide superior strength and rebound characteristics. The outer layers are embossed and coated with a high-temperature Viton rubber, capable of withstanding temperatures up to 250°C (482°F). This advanced design is perfect for managing the shearing forces between aluminum cylinder heads and engine blocks.
Whether you are building a street-legal daily driver or a dedicated track weapon, this Cometic gasket ensures your engine stays sealed under the most demanding conditions. Trust the precision of Cometic engineering to protect your Subaru build. Find all your essential engine internals and performance gaskets at GGCRACING.
