Cometic multi-layer steel (MLS) headgaskets for the for the Subaru 2.0L & 2.5L EJ series turbo engines are comprised of three layers of stainless steel. Cometic uses stainless steel for increased strength, it's ability to rebound, and improved corrosion resistance.

Cometic's Viton coating is heat resistant to 250 degrees celcius or 482 degrees farenheit. By design the MLS gasket promotes an even torque across the sealing surface allowing for measurable reduced bore distortion. Price is for a pair gaskets, select engine, bore, & thickness below.
