Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with embossed stainless steel layers, featuring Viton rubber coating on the outer surfaces. The compressed operating thickness is .045 inches, and it's designed for an 80mm bore, making it a solid choice for your 1988-1993 Mazda 323, as well as compatible MX-3, Miata, and Mercury Capri models with the B6D, B6T, or B6ZE engine.

MLS gaskets are known for their strength and ability to handle the demands of high-output engines. The multiple stainless steel layers provide rebound resistance and help prevent corrosion. The Viton coating on the outer layers is heat-resistant up to 482°F (250°C) and is designed to seal effectively in harsh environments, even with different block and head materials like aluminum to cast iron. This construction means you won't need additional sealants for installation.

The center shim layer is also stainless steel and can be varied to achieve different thickness requirements, though this specific gasket is set at .045 inches compressed thickness. This gasket is a well-built option for rebuilding or replacing your engine's cylinder head seal.
