Cometic Mazda MZR 2.3L 87.5-89mm Bore .040in MLS Head Gasket

When you're rebuilding the top end of your Mazda 3, 5, 6, or CX-7, a reliable head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of modern engines, offering a strong seal without needing extra sealants.

Cometic constructs this gasket using multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and various sealing conditions. The center layer is stainless steel, and its thickness can be adjusted to meet different requirements, with this specific gasket having a compressed operating thickness of 0.040 inches. This design makes it suitable for sealing between aluminum heads and either aluminum or cast iron blocks, effectively managing the stresses that can occur between dissimilar metals.
