Cometic Mitsubishi 4G63/T 85.5mm .027 inch MLS Head Gasket Eclipse / Galant/ Lancer Thru EVO3

If you're working on the 4G63 or 4G63T engine in your 1990-1999 Mitsubishi Eclipse, Galant, or Lancer, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice. It's built to handle the demands of high-output engines, offering a reliable seal without needing any extra sealants. This gasket is designed to work well whether you have aluminum heads with an aluminum block or aluminum heads with a cast iron block, as the multiple steel layers can manage the different expansion rates between those materials.

Cometic constructs these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating helps ensure a good seal even in tough conditions and on various surface finishes. The center layer is stainless steel and can be varied in thickness; in this case, it's set to provide a compressed operating thickness of 0.027 inches, with an 85.5mm bore to match your engine.
