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. If you're working on a 1996-2005 Mitsubishi Lancer Evolution 4-8 with the 4G63 engine, or a 2003-2018 Toyota 4Runner, Tacoma, or Tundra, this gasket is built to handle the demands of high-output engines.

This MLS gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in tough sealing environments. The compressed thickness is 0.036 inches, and it has an 87mm bore, making it suitable for specific engine builds. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation.
