About this part

Product Details

If you're working on the 1GR-FE engine in your 2003-2018 Toyota 4Runner, FJ Cruiser, Tacoma, or Tundra, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for the right side. 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 it 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 coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is tough and designed to seal effectively even under challenging conditions and on various surface finishes. The center layer is also stainless steel, and its thickness can be varied to achieve specific compressed operating thicknesses, like the .027 inches on this particular gasket.
