About this part

Product Details

If you're rebuilding the top end of your Toyota 2ZZ-GE engine, this Cometic MLX head gasket is a solid option. It's designed for an 82.5mm bore and has a compressed thickness of .040 inches, making it suitable for a range of performance applications and engine builds. This gasket fits many vehicles, including the Toyota Celica, Corolla, Matrix, Pontiac Vibe, Lotus Elise, and Exige.

Cometic builds these gaskets using multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes, ensuring a good seal without needing extra sealants. The center layer is also stainless steel, and Cometic can vary this layer to achieve different thicknesses, like the .040" on this particular gasket, to meet specific engine build requirements.
